Sandro had 8 cups of cocoa. He uses 1/ 4 cup of cocoa for one batch of cookies. How many batches of cookies can she bake if she uses all the cocoa?

Question

This is my homework question can someone help

Answer 1

Basically the question is asking you to determine how many QUARTER-CUPS are in 8 cups. We can translate this into a sentence:

8 divided by 1/4 is ?

we can use that sentence to write the equation

8 [division symbol or divided by] 1/4

then change 8 into a fraction

8/1 [division symbol] 1/4

remember to divide fractions we keep, switch, flip and multiply (or in older textbook terms, invert the second fraction and multiply) so now the equation is 8/1 [times symbol] 4/1

to multiply fractions, remember you just multiply numerators and denominations straight across, so

8 times 4 is 32 (that is your numerator in your answer)

1 times 1 is 1 (that is your denominator in your answer)

your answer is 32/1 or which simplifies to 32

so 32 batches of cookies can be made.

(CHECK: four one-quarter cups make 1 cup and that would make 4 batches; 4 times 8 cups (all of the cocoa) makes 32, so the answer makes sense)

Answer 2

There are 8 cups. Each batch of cookies uses 1/4 of a cup to make. If you used all the cocoa you would use 8 cups. First you have to figure out how many 1/4 cups are in 1 cup. To get 4/4 there would be 1/4+1/4+1/4+1/4. So she can make 4 batches for every cup she has. You would then multiple 4 which is how many per cup and 8 which is total amount of cups. So your answer would be 32 batches.
