Put in simplest form 8/15 * 5/6

8/15 = 16/30

5/6 = 25/30

(16x25) / (30x30)

400/900 = 4/9 is you answer

8/15 x 5/6

•multiply across the numerator and denominator.

= 40/90

• then find a common factor that will go into both the numerator and denominator equally.

Common factor: 5

= 8/18

•there is another common factor, which is 2

Simplified:
