To covert:
(8)/(10)*(100)/(1)
Reduce the expression (8)/(10) by removing a factor of 2 from the numerator and denominator.
(4)/(5)*(100)/(1)
Reduce the expression by removing the common factor of 5 in the denominator of the first term (4)/(5) and the second term 100.
4*20
Multiply 4 by 20 to get 80.
80
You can do the rest with the same equation; every fraction is multiplied by 100/1
