Question

Ed has a recipe that uses ac{2}{3}" align="absmiddle" class="latex-formula"> cup of flour for each batch. If he makes 4 batches, how many cups of flour will he need? Answer in a fraction pls! Will give brainliest!

Answer 1

Answer as an improper fraction:  8/3

This converts to the mixed number 2 & 2/3

So he'll need 2 whole cups plus another 2/3 of a cup.

===========================================================

Explanation:

1 batch uses 2/3 of a cup

4 batches uses 4*(2/3) = (4/1)*(2/3) = (4*2)/(1*3) = 8/3 of a cup

Simply multiply 2/3 by 4 to get 8/3.

-----------

If you need to convert to a mixed number, then you could follow these steps

8/3 = (6+2)/3

8/3 = 6/3 + 2/3

8/3 = 2 + 2/3

8/3 = 2 & 2/3

Or you could note that 8/3 = 2.667 approximately. The decimal portion 0.667 converts to the fraction 2/3.

Answer 2

Answer:

The formula for this would be $2/3 \times4$

Since we need to multiply the fraction against the amount of batches, to get the final result of cups of flours. (It only makes sense!)

8/3 is the correct answer

2 2/3 is the mixed fraction
