3/5 multiplied by x/1500
let x = a
= (3 x a) / (5 x 1500)
= 3 can divide 1500 >> so u are left with 500
Therefore
= 3a/3 / 5 x 1500/3
= a/ 5 x 500
= a/2500

Multiply the two numerators (top) by each other. Multiply the two denominators (bottom) by each other. = (3x)/(1500*5) =
3x/(7500).
Does 7500 divide by 3? Yes.
Therefore, simplify the fraction by dividing the numerator and denominator by 3. (This is the same as dividing by [3/3], ie 1).
Gives you x/2500
