Which ratio is equivalent to the unit rate
2 answers:
It would be D.) because you multiply the ratio 30:1 by 6
Answer D is correct. The ratio 30 miles:1 gallon multiplied by 6 is 180 miles:6 gallons
Option A: Divide each by 10 and you will get 10 miles and 3 gallons. That is false. You would get 3 miles and 0.1 gallons.
Option B: Multiply the ratio by 3 to get 90 miles and 5 gallons. This is also false. If you multiply by three you would get 90 miles and 3 gallons.
Option C: Multiply by 2 to get 180 miles and 6 gallons. This is wrong. Multiplying 30 miles and 1 gallon by 2 is 60 miles and two gallons
Option D: Multiply by 6 to get 180 miles and 6 gallons. This works because 30x6=180 and 1x6=6.
Multiply both sides of the ratio by the same number to get an equivalent ratio.

-3n= -3n
6n= -12
divide by 6 = -2 =n
to check.. 9 times -2 = -18 soo.. 3 times -2= -6-12= -18
so it is correct!!
