What is 8/10 minus 1/2?

8/10-1/2

You need to find a common denominator and that would be 20.

You need to do 8*2=16 to find the first numerator.

Then 10*1=10 to find the second one, so far we have

16/20 - 10/20

Then we keep the first fraction change the signto multiply and flip the second fraction to give:

16/20*20/10

8/1 multiply 1/5

Then we multiply 8 and 1 to give 8 and 5 and 1 to give 5.

The final fraction is 8/5.

If you want it as an improper fraction then it would be 1 whole and 3/5
