Question

A line plot.Short description, A line plot.,Long description,
A line plot shows Weight of Packages from 1 to 2 pounds.

1 mark is at 1 and 1 eighth pound.
2 marks are at 1 and 3 eighths pound.
3 marks are at 1 and 1 half pound.
3 marks are at 1 and 3 quarters pound.
1 mark is at 2 pounds.

Question
How many more pounds are all the packages that weigh 1 and 3-fourths pounds than all the packages that weigh 1 and 3-eighths?

Answer 1

To find the total weight of the packages that weigh 1 and 3-fourths pounds, we need to multiply the weight by the number of packages at that weight.

There are three packages that weigh 1 and 3-quarters pounds, so the total weight for those packages is 3 * 1.75 = 5.25 pounds.

Similarly, there are two packages that weigh 1 and 3-eighths pounds, so the total weight for those packages is 2 * 1.375 = 2.75 pounds.

Therefore, the packages that weigh 1 and 3-fourths pounds weigh a total of 5.25 pounds and the packages that weigh 1 and 3-eighths pounds weigh a total of 2.75 pounds.

To find the difference, we subtract the weight of the 1 and 3-eighths pound packages from the weight of the 1 and 3-fourths pound packages:

5.25 - 2.75 = 2.5

Therefore, the packages that weigh 1 and 3-fourths pounds weigh 2.5 more pounds than the packages that weigh 1 and 3-eighths pounds.
