Correct Answers only please!

A student sketched some art on an 8.5 inch x 11 inch piece of paper. He wants to resize it to fit an 5 inch x 7 inch frame (as shown below)


What is the value of x? (Hint: Like Step #1 of the example in class)



A. x = 5


B. x = 6


C. x = 5.41


D. x = 7

Answer 1

x = 5.41

Explanation:

The picture is originally 11 inches wide by 8.5 inches tall. It gets scaled down to a new width of 7 inches. We need to find the new height. To do this, we write a proportion:

8.5 / 11 = x / 7

Cross multiply:

11x = 59.5

Divide:

x = 5.41
