Problem 1.1 A Question 3 The ratio of 17, 139 to 11, 426 THINK: round to compatible numbers rounded up to 18,000 and 11, 426 rounded up to 12,000…what is that reduced? The ratio of 3 to 2 (a part to part comparison) could also be written as 3 to 5 ( a part to whole) comparison. 3 to 5 is 60% The difference between 17, 139 and 11, 426 is 5,713.

Problem 1.1 A Question times as many people preferred Bolda Cola to Cola Nola (like the Samsung commercial made a comparison) 6 out of 10 people preferred Bolda Cola to Cola Nola

Problem 1.1 B Question 3 and kids surveyed 50 prefer a concert 100 prefer an athletic event 1.Yes. 50/150 would reduce to 1/3 2.Yes. 100:50 = 2:1 3.Yes. 50: 100 = 1:2 4.Yes = 50

Problem 1.1 B Question 5 and kids surveyed 50 prefer a concert 100 prefer an athletic event 1.Yes. 50/150 would reduce to 1/3 2.Yes. 100:50 = 2:1 3.Yes. 50: 100 = 1:2 4.Yes = 50 5.Yes. 100 = 2 x 50 6.No. About 33% of students prefer concert to athletic event
