Seven out of every eight students surveyed owns a bike the difference between the numbers of students who own a bike and those who do not is 72 how many students were surveyed

Step-by-step explanation:

Proportions

Variables are proportional if one of them can be obtained as the other by a constant number.

Let's suppose a number of x students were surveyed. Seven out of every eight students own a bike. It means that

surveyed students own a bike

surveyed students do not own a bike

The difference between both quantities is

We know that number is 72

 96 students were surveyed (84 of them own a bike, 12 don't)

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
