Question

how much longer is 1 and 1/4 than 3/8

Answer 1

Hi Ashley!

In order to answer this, we need to do a couple of steps. First, we need to turn 1 1/4 into an improper fraction and then we need to set up common denominators.

Improper Fractions:

1 = 4/4, so 1 and 1/4 is equivalent to 5/4

Common Denominators:

A common multiple between our denominators is 8, so we need to set our common denominator as 8.

5/4 becomes 10/8 (since we multiply the numerator and denominator by 2) and then 3/8 can stay the same.

10/8 - 3/8 = 7/8 (subtract across)

So, 1 1/4 is 7/8 longer than 3/8. Hope this helps!!

Answer 2

1 and 1/4 minus 3/8 = 1 and 2/8 minus 3/8

= 10/8 - 3/8

= 7/8

CHECKING:

Does 7/8 + 3/8 = 1 1/4?

7/8 + 3/8 = 10/8

= 5/4

= 1 1/4

Hope this was helpful Ashley.
