What is the difference in length between 1 1/4 in and 3/8 inch

Answer 1

First convert 1 1/4 to improper fraction. (1*4 + 1)/4 = 5/4

Then change 5/4 so it has the same denominator as 3/8, by multiplying top and bottom of 5/4 by 2:

5*2 = 10

----- ---

4*2 8

so now we have:

10 - 3

---- ----

8 8

since same denominator

10 - 3 = 7

-------- ----

8 8
