A banana bread recipe that makes 4 loaves calls for 12 bananas . If Bruce is making 24 loặves, how many bananas does he need?

## Step 1<br />This problem involves the concept of ratios and proportions. The given information is that 12 bananas are needed for 4 loaves of bread. We are asked to find out how many bananas are needed for 24 loaves. <br /><br />## Step 2<br />We can set up a proportion to solve this problem. The proportion is 12 bananas/4 loaves = x bananas/24 loaves. <br /><br />## Step 3<br />To solve for x, we can cross-multiply. This gives us 12 bananas * 24 loaves = 4 loaves * x bananas. <br /><br />## Step 4<br />Solving this equation for x gives us x = 72. Therefore, Bruce needs 72 bananas to make 24 loaves of bread.
