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
