Sandy uses 2/7of a pound of raisins in each batch of raisin bread. Yesterday, Sandy used 5/7 of a pound of raisins. How many batches of raisin bread did Sandy make yesterday!

no

2/7 lb of raisins bakes 1 batch of bread
1 lb of raisins makes 1/(2/7) or 7/2 batches of bread
so 5/7 lbs of raisins makes (5/7)(7/2) or 5/2 batches of bread,
which is 2 1/2 batches of bread , or 2.5 batches

To find the number of batches of raisin bread Sandy made yesterday, we need to divide the total weight of raisins used (5/7 pound) by the weight of raisins used in each batch (2/7 pound).

To perform the division, we can use the following steps:

Step 1: Convert the fractions into decimals.
5/7 pound = 0.714 pounds
2/7 pound = 0.286 pounds

Step 2: Divide the total weight of raisins used by the weight of raisins used in each batch.
0.714 pounds ÷ 0.286 pounds = 2.5

Therefore, Sandy made 2.5 batches of raisin bread yesterday. However, since we cannot have a fraction of a batch, we need to round the answer to the nearest whole number.

Rounding 2.5 to the nearest whole number gives us 3.

So, Sandy made 3 batches of raisin bread yesterday.
