Inferences for Proportions

A total of 70 students out of 350 students in the 7th grade bought snacks during the last Eagle's nest. Based on this information, make a prediction about how many students in the school bought snacks during Eagle's Nest when there are 1050 students in the school.

• 210

• 350

• 525

• 700

Which of the following would represent a proportional relationship?

• Phil uses 2 cups to make 5 loaves and Jemma uses 3 cups to make 7 loaves.

• Jo reads 25 pages in 6 minutes and Bree reads 40 pages in 10 minutes.

• Cecil decorates 5 cupcakes in 10 minutes and Ava decorates 8 cupcakes in 16 minutes.

Form ratios and a proportion out of the picture above.

• 3 : 6, 6 : 3 and 3 : 6 = 6 : 3

• 6 : 3, 2 : 1 and 6 : 3 = 2 : 1

• 3 : 6, 1 : 2 and 3 : 6 = 6 : 3

• 1 : 2, 3 : 6 and 3 : 2 = 1 : 6

Form ratios and a proportion out of the picture above.

• 10 : 150, 1 : 15 and 10 : 150 = 1: 15

• 1 : 150, 1 : 15 and 1 : 150 = 1 : 2

• 10 : 150, 10 : 2 and 10 : 150 = 10 : 2

• 1 : 2, 10 : 150 and 1 : 2 = 10: 150
