Ratio - a comparison of two quantities by division. Can be written 3 different ways. 200 200 Miles 200 : 4 200 to 4 4 4 Hours • Rate – Ratio that compares 2 quantities measured in different units 200 Miles : 4 Hours 200 Miles to 4 Hours
Ex 1) A basket of fruit contains 6 apples, 4 bananas, and 3 kiwi. Write a ratio in all 3 forms for the following: 4 b A. Bananas to kiwi 1. Write the first quantity on top with a label 3 k 3 k B. Kiwito bananas 2. Simplify, but do not convert to a proper fraction 4 b 2 b 4 b C. Bananas to apples = 6 a 3 a 6 a 2 a = D. Apples to Kiwi 3 k 1 k
A unit rate is a rate whose denominator is 1. To change a rate to a unit rate, divide both the numerator and denominator by the denominator. 50 Miles = 200 Miles 1 Hour 4 Hours Ex 2) During exercise, Paul’s heart beats 675 times in 5 minutes. How many times does it beat per minute? 675 beats 675 beats ÷ 135 beats 5 = ÷ 5 1 minute 5 minutes
Ex 3) The Millers want to drive the 288 miles to Rainbow Falls in 6 hours. What should their average speed be in miles per hour? 288 miles ÷ 48 miles 6 = ÷ 6 1 hour 6 hours
