Answer 2

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

Explanation:

Givens

• Mina has 4/5 of the flour she needs to make a loaf of bread.
• 1 loaf of bread requires the same amount of flour than 12 rolls.

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.

`x=(4)/(5) \ flour * (12 rolls)/(1 \ flour)= 9.6`

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.
