Subtract 8/10 from 4/10 but just the numerator (the top number) and you will get 4/10
60/100 = 8/x
Multiply both sides by 100
60 = 800/x
Multiply both sides by x
60x = 800
Divide both sides by 60
x = 13.3333333333333
0.3 • x = answer
Answer = 4

Literally the roots equal 0. Is that “X” or the multiplication sign? Because I did it with “X” and it gave me “0”
