Subtract. Write your answer as a fraction in simplest form. 3 3/4 - 7/8

Answers

I find that fractions can be tricky, so I convert them to decimals before subtracting.

3 3/4 = 3.75

7/8 = 0.875

3.75 - 0.875 = 2.875

Knowing that 0.875 = 7/8, we now know that our answer is 2 7/8.

Hope this helps!
