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
The things that are diagonal to each other we can simplify. For example 20÷20=1
Fraction simplified:
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
