Question

A survey found that 68% of students do their homework before 10:00 P.M. Predict how many students out of 1,095 do their homework before 10:00 P.M.

Answer 1

744.6 or if you round it 745

Explanation:

Step 1: Divide 1095 by 100

In this case, the number that we are "comparing" to 100 is 1095, so we must first normalize the number by dividing it by 100. The operation we have to solve is this:

1095/100= 1095÷100= 10.95

Step 2: Multiply 10.95 by 68 to get the solution

Now that we have our normalized number, 10.95, we just have to multiply it by 68 to get our final answer. The forumla for this is obviously quite simple:

10.95×68= 744.6
