Express Each Ratio as unit rate, 1- 120 Feet in 4 Minutes 2- 4 mangoes for 120 3- 114 per 2 liters of gasoline 4- 8 pounds lost in 4 weeks, with solution
1- 30 feet per minute
2- 30 mangoes per minute
3- 57 per liter of gasoline
4- 2 pounds per week
To express each ratio as a unit rate, you need to simplify the ratio to a single unit of the first quantity per one unit of the second quantity. Let's go through each ratio and express it as a unit rate:
1. 120 feet in 4 minutes:
To find the unit rate, divide the total feet by the total minutes.
Unit rate = 120 feet ÷ 4 minutes = 30 feet per minute
Therefore, the unit rate for this ratio is 30 feet per minute.
2. 4 mangoes for 120:
To express this ratio as a unit rate, divide the number of mangoes by the given quantity.
Unit rate = 4 mangoes ÷ 120 = 1 mango per 30
The unit rate for this ratio is 1 mango per 30.
3. 114 per 2 liters of gasoline:
To find the unit rate, divide the given quantity by the first quantity.
Unit rate = 114 ÷ 2 = 57 per 1
Therefore, the unit rate for this ratio is 57 per 1.
4. 8 pounds lost in 4 weeks:
To express this ratio as a unit rate, divide the number of pounds lost by the given quantity.
Unit rate = 8 pounds ÷ 4 weeks = 2 pounds per week
The unit rate for this ratio is 2 pounds per week.
1- To express the ratio "120 feet in 4 minutes" as a unit rate, you need to divide the total number of feet by the total number of minutes. So, the unit rate would be:
120 feet / 4 minutes = 30 feet per minute
2- To express the ratio "4 mangoes for 120" as a unit rate, you need to divide the total number of mangoes by the total number given. So, the unit rate would be:
4 mangoes / 120 = 1 mango per 30
3- To express the ratio "114 per 2 liters of gasoline" as a unit rate, you need to divide the total number given by the total number of liters. So, the unit rate would be:
114 / 2 = 57 per liter of gasoline
4- To express the ratio "8 pounds lost in 4 weeks" as a unit rate, you need to divide the total number of pounds by the total number of weeks. So, the unit rate would be:
8 pounds / 4 weeks = 2 pounds per week
