Which fraction expresses 36/80 in lowest terms? Please help me ;D

JulijaS [17]

To reduce a fraction to lowest terms (also called its simplest form), divide both the numerator and denominator by the GCD. For example, 2/3 is in lowest form, but 4/6 is not in lowest form (the GCD of 4 and 6 is 2) and 4/6 can be expressed as 2/3.

38/80= 19/40
