The length of the longest piece of bread is 1405 and 1 3\4. It was cut into slices 1\2 in thick how many slices were there?
To find the number of slices, we need to divide the length of the longest piece of bread by the thickness of each slice.
Step 1: Convert the mixed number 1 3/4 to an improper fraction.
1 3/4 = 1 + 3/4 = 4/4 + 3/4 = 7/4
Step 2: Add the whole number and fraction together to get the total thickness.
1/2 + 7/4 = 2/4 + 7/4 = 9/4
Step 3: Divide the length of the longest piece of bread by the thickness of each slice to find the number of slices.
1405 1 3/4 ÷ 9/4 = (1405 * 4 + 1 * 4 + 3)/9 = (5620 + 4 + 3)/9 = 5627/9
Therefore, there were 5627/9 slices of bread.
