15/27 * 18/35 find each product

15/27=0.556

18/35=0.5143

0.556x0.5143=0.286

If your question is find the product if the two fractions then:

15 x 18 = 270

27 x 35 = 945

your answer is 270/945, but is not simplified.

To do that divide each number by their greatest common factors. If you don't know what that means, divide both by a number they can both evenly be divided by. (such as 5):

270/5 = 54

945/5 = 189

repeats this with more number they both share: like 27

54/27 = 2

189/27 = 7

your final answer is 2/7
