Question

Every time Mary bakes a batch of brownies, she uses 15 cup of chocolate. If she has 8/10 cup(s) of chocolate remaining, how many batches of brownies can Mary make? Input your answer as a whole number.

Answer 1

Given :

1 batch of brownies required 15 cup of chocolate.

To Find :

If she has 8/10 cup of chocolate remaining, how many batches of brownies can Mary make.

Solution :

Ratio of cups to batch is :

$R=\dfrac{15}{1}$

Let , batch produced from 8/10 cup of chocolate is x.

So ,

$\dfrac{\dfrac{8}{10}}{x}=\dfrac{15}{1}\\\\x=\dfrac{8}{10\times 15}\\\\x=0.053\ batches$

Therefore , she can make 0.053 of a batch.

Hence , this is the required solution.
