Question

What's is 1 3/8 - 3/4

Answer 1

Given the following expression:

`1(3)/(8)-(3)/(4)`

To subtract the numbers, we need to convert the mixed number to a fraction number

`1(3)/(8)=(8*1+3)/(8)=(11)/(8)`

And then, we need to make both fractions have the same denominator

The common denominator for 4 and 8 will be 8

`\begin{gathered} (11)/(8)=(11)/(8) \\ \\ (3)/(4)=(3*2)/(4*2)=(6)/(8) \end{gathered}`

So, the subtraction process will be as follows:

`1(3)/(8)-(3)/(4)=(11)/(8)-(6)/(8)=(11-6)/(8)=(5)/(8)`

So, the answer will be 5/8
