Question 338029
the product of two numbers is 90. if one of the numbers is 15/16, what is the number?


you first need to set up the equation in fraction form...

90/1÷15/16

the first rule of dividing fractions is that you must multiply the reciprocol of the second set of numbers

90/1 x 16/15

multiply 90 x 16
and multiply 1 x 15

90x16=1440
1x15=15

your answer is 1440/15
simplify your answer 1440÷15= 96

your answer is 96
