Hello. The percentage of the dried apricot that is water is 60%.
We knew the water content of an apricot, by weight, is 80%. A dried apricot loses 75% of its water content, so we knew that we had to multiply 0.75 by 0.8 to find 75% of 80%.
0.75 x 0.8 = 0.6 0.8 - 0.6 = 0.2 We know that you can convert a decimal into a percentage by multiplying it by 100. 0.2 x 100 = 20%
Therefore, the water content of a dried apricot is 20%.
Before we decided on an answer, we considered many different forms of mathematical strategies/techniques/methods we could use to do so. In the end, we utilized the 'Discount/Tax' method:
e.g
SALE! 50% all items!
Jacket - $10.00
50% of $10.00
.50 x 10 = 5
When we found 50% of 10 (let's call it n), the value of n represents the number that we have to subtract from 10.
10 - 5 = 5. Therefore, 50% of 10 is 5. Or 1/2 of 10.
Hi there, Emily here again! So from what I know, I'm pretty sure the answer would be 20%. So basically, how I got it was that I saw 80% as 80, and found 75% of 80, which was 60. So 60 would be 75%, which is correct so far.
75% is just 25% from 100%, and 25% goes into 75% 3 times, so 60 divided by 3 is 20, or 25%. Since the apricot loses 75% of water, then 25% is lost, meaning that 20 is the answer. BUT WAIT! 20 is not correct, I would need to covert back to percent for this answer to be answered, so 20=20%! SO technically, the ratio would be reversed! 80:20 to 20:80 So that's how I got my answer! The percent of water inside a dried apricot would be 20% This answer was quite short, considering the fact that my past one was longer and other people's answers are long as well, so I hope I explained enough for anyone out there to understand. :)
Yello mates, To find the answer, You first had to multiply the weight of the dried apricot before it went to the sun (80%) to the dried apricot after it went in the sun (75%)
So first you had to change in to decimals 80%= 0.80. 75% = 0.75 So 0.80 x 0.75 = 0.6
So now you know that 75% of 80% is 0.6 Now you had to subtract the total amount of water in the apricot to 0.6 0.80 - 0.60 = 0.20 Since before we change percentage to decimals because we had to calculate now we have to change the decimals back to percentage. So 0.20 = 20% In total, after being left in the sun, 20% of the apricot is water Peace lads and have a nice day
Yello mates To find the answer you have to first multiply the dried apricot before it went to the sun (80%) to the dried apricot on how much water it lost when went in the sun (75%). But first you have to change it to decimals to calculate. 80% = 0.80 75%= 0.75 0.80 x 0.75 = 0.6 So after, you have to subtract the total amount of water inside the dried apricot before it went to the sun to 0.6 0.80 - 0.6 = 0.20 Since I have switch the percentage to decimals to calculate, now we have to switch decimal back to percentage. 0.20 = 20% After in going to the sun, the final answer is 20% Peace lads and have a nice day!
First of all... nice job with the enthusiastic words! Second of all... i see what you did there lad! Third of all... Thank you for contributing to our blog! Fourth of all... I now this __________ of all is getting boring. So, bye! Or as John says... Peace lads and have a nice day!
Ah this was a tricky one eh kids. Please see the answer below.
Let's consider an apricot that originally weighs 100 g. If 80% of the weight is water, that means that 80 g is water and 20 g is other material. When left in the sun, the apricot loses 75% of its water weight. So it loses 75% of 80 g = 0.75 x 80 = 60 g of water, and 80 - 60 = 20 g of water remains. The dried apricot is still 20 g of other material. Therefore, the dried apricot consists of 20 g of water and 20 g other material. The dried apricot is therefore 50% water.
first of all, love the conversations that are happening here! great stuff...
to break this questions down, essentially you are figuring out what's 75% of the original 80% of water...which is 3/4 of 80% > 20% of the original mass ....now also equal to the non-water content (20%); therefore in the dried apricot, the water and non-water content is now equal, thus a 50-50 split... =)

ReplyDeleteHello. The percentage of the dried apricot that is water is 60%.
ReplyDeleteWe knew the water content of an apricot, by weight, is 80%. A dried apricot loses 75% of its water content, so we knew that we had to multiply 0.75 by 0.8 to find 75% of 80%.
0.75 x 0.8 = 0.6
0.8 - 0.6 = 0.2
We know that you can convert a decimal into a percentage by multiplying it by 100.
0.2 x 100 = 20%
Therefore, the water content of a dried apricot is 20%.
-Rachel and Jonathan
why 0.8 minus 0.6
DeleteOh!
DeleteI see what u did there!
Now I know my answer is wrong!
Whoops!
Oh we forgot to mention this in our answer.
DeleteSince we can't just find a % of %, we have to convert it into an equivalent decimal.
Percent --> Decimal = ? / 100

Since before we change percentage to decimals because we had to calculate now we have to change the decimals back to percentage.
So 0.20 = 20%
In total, after being left in the sun, 20% of the apricot is water

ReplyDeleteLet's consider an apricot that originally weighs 100 g. If 80% of the weight is
water, that means that 80 g is water and 20 g is other material.
When left in the sun, the apricot loses 75% of its water weight. So it loses
75% of 80 g = 0.75 x 80 = 60 g of water, and 80 - 60 = 20 g of water remains.
The dried apricot is still 20 g of other material. Therefore, the dried apricot
consists of 20 g of water and 20 g other material.
The dried apricot is therefore 50% water.
