Mina has 4/5 of the flour she needs to make a loaf of bread. It takes the same amount of flour to make 1 loaf of bread as it takes to make 12 rolls. What is the greatest number of rolls Mina can make with the flour she has?

A. 8 Rolls

B. 9 Rolls

C. 10 Rolls

Step-by-step explanation:

Givens

Basically, the problem states that with the complete flour, which is 5/5, Mina can make 12 rolls or 1 loaf of bread. Using the rule of three, if 5/5 is equivalent to 12 rolls, how many rolls would be 4/5 of the flour.

Therefore, Mina can make 9 rolls with 4/5 of flour.

(Notice that the result is 9.6, however we can't use the approximation 10, because that would imply an incomplete roll.
