6th Grade Unit Rates and Rate Language Quiz: 10 Questions with Explanations

A $1.25B $0.80C $0.20D $9.00

\(\$4.00 \div 5 = \$0.80\). Dividing 5 by 4 gives $1.25, which flips the division.

A 108 miles per hourB 33 miles per hourC 1/12 miles per hourD 12 miles per hour

Divide distance by time: \(36 \div 3 = 12\). Multiplying (108) is a common mistake.

A Store CB Store AC Store BD All three are equal

A is $0.75 per can, B is $0.80, and C is $0.70. Store C is lowest.

A 8B 80C 60D 288

The unit rate is \(48 \div 6 = 8\) toys per hour, so \(8 \times 10 = 80\). Multiplying 48 by 6 gives 288.

A For every 1 gallon, 4.5 minutes passB For every 4.5 minutes, 1 gallon flowsC For every 45 minutes, 1 gallon flowsD For every 1 minute, 4.5 gallons flow

The word “per” tells which quantity is 1. Here it is 1 minute.

A $4.00B $0.40C $0.25D $36.00

Divide the cost by the ounces: \(3.00 \div 12 = 0.25\).

A 35 minutesB 8 minutesC 200 minutesD 1/8 minute

Divide the time by the miles: \(40 \div 5 = 8\).

A 3 miles per hourB 3/16 miles per hourC 1 mile per hourD 1/3 miles per hour

3/\(4 \div 1\)/\(4 = 3\)/\(4 \times 4 = 3\). The product of the fractions is 3/16, which is not a rate.

A $42B $6C $21D $54

Each pizza is \(\$18 \div 3 = \$6\). Then \(7 \times \$6 = \$42\).

A Car A at 50 miles per hourB Car C at 40 miles per hourC Car B at 55 miles per hourD Car B at 60 miles per hour

A is 50, B is 55, and C is 40 miles per hour. Car B is fastest.
