What is answer to 4/5 - 1/10

Answer: 7/10

0.70000 as a decimal

4/5-1/10=7/10

First, you have to find a common denominator (which is 10 in this case) : 5x2=10, and you do the same to the numerator: 4x2=8

This turns the equation into: 8/10-1/10

Since they have the same denominator, you can just subtract the numerator: 8/10-1/10=7/10
