26 25

Practice makes perfect
Before we evaluate the expression, let's first rewrite the expression so that all of the numbers are fractions.
1 115* 5 25* 4 712
1* 15+ 1/15* 5* 5+2/5* 4*12+7/12
15+ 1/15* 25+2/5* 48+7/12
16/15* 27/5* 55/12
When we multiply fractions, we need to remember that the product of two fractions is equal to the product of the numerators divided by the product of the denominators. Let's find the given product!
16/15* 27/5* 55/12
16* 27/15* 5* 55/12
16* 27* 55/15* 5* 12
23 760/900
The quotient is 23 760900. We can also write this fraction as a mixed number.
23 760/900
23 400+360/900
23 400/900+360/900
26+360/900
26+360Ă· 180/900Ă· 180
26+2/5
