To find the unit rate, solve 2 ÷ 7 to get a decimal that rounds to 0.3. This means there are about 0.3 triangles for every 1 circle. You can also reverse this by stating the unit rate in terms of the ratio of circles to squares (7:2 or 7/2). Since 7 ÷ 2 = 3.5, you can also say there are 3.5 circles for every 1 triangle.

Hard ratio word problems. Example #4: Suppose the width of a soccer field 60 meters and the length is 100 meters. What is the ratio in simplest form of the length to the area of the field? Solution: The area of the field is 60 × 100 = 6000 The ratio of the length to the area is 100 to 6000, 100:6000 or 100/6000. 100/6000 = 1/60 The ratio of the length to the area in simplest form is 1/60In proportions, since the two ratios are equal, you can cross-multiply and get the same answer. Ex.: = 2100 30 70 2100 21 100 Same Ex.: 6 is 50% of 12 100 50 = 12 6 600 12 50 600 6 100 Solving percent problems for the unknown You will be able to use cross multiplication to solve all percent problems where one of the three numbers is missing.

Textbook Authors: Charles, Randall I., ISBN-10: 0133281159, ISBN-13: 978-0-13328-115-6, Publisher: Prentice Hall A unit rate is also called a unit ratio. (They mean the same thing.) $\frac{5}{4}$ and $3:8$ and $40\mbox{ to }10$ are ratios, but they are not unit ratios. $\frac{1.25}{1}$ and $0.375:1$ and $4\mbox{ to }1$ are unit ratios. Any ratio can be converted into a unit ratio by dividing the numerator and the denominator by the denominator.
