What is (11*12)/(15*7) ?
Answered by me
To find the product of two fractions, you simply multiply across top & bottom.

But first, you can see that 12 and 15 have a common factor of 3.

So, (11 / 15) * (12 / 7) then becomes:
(11 / 5) * (4 * 7)

Multiplying straight across, you get:
(11 * 4) / (5 * 7)
= 44 / 35
