Question: 1 / 440

What is the sum of the following measurements: 7/8", 3/4", 1/2", and 3/8"?

2 inches

2 1/4 inches

2 1/2 inches

To find the sum of the measurements 7/8", 3/4", 1/2", and 3/8", it is helpful to convert all the fractions to a common denominator. The smallest common denominator for these fractions is 8.

1. Start by converting each fraction:

- 7/8 remains 7/8.

- 3/4 can be converted to eighths: \(3/4 = (3 \times 2)/(4 \times 2) = 6/8\).

- 1/2 can be converted to eighths: \(1/2 = (1 \times 4)/(2 \times 4) = 4/8\).

- 3/8 remains 3/8.

2. Now the fractions to be summed are:

- 7/8 + 6/8 + 4/8 + 3/8.

3. Adding these together:

- \(7/8 + 6/8 = 13/8\)

- \(13/8 + 4/8 = 17/8\)

- \(17/8 + 3/8 = 20/8
