Which ratio is equivalent to the unit rate
30 miles/ 1 gallon
? Explain how the unit rate is transformed into the equivalent ratio.
A) 3 gallons/10 miles
; by dividing the numerator and denominator of the unit rate by 10.
B) 90 miles/5 gallons
; by multiplying the numerator and denominator of the unit rate by 3.
C) 6 gallons/180 miles
; by multiplying the numerator and denominator of the unit rate by 2.
D) 180 miles/6 gallons
; by multiplying the numerator and denominator of the unit rate by 6.
180 / 6 simplified is 30 / 1. Although C has the same numbers, the numbers are switched. 6 / 180 simplified would be 1 / 30. This is not the same as 30 / 1.
