Question

Medal
The price of gasoline jumped from $1.02 per Litre to $1.36 per Litre in 1 year. What is the ratio of the increase in price to the original price, expressed as a fraction in lowest terms?

Answer 1

\[Increase=\frac{|was-is Now|}{was}\]

Answer 2

i dont understand

Answer 3

was = what the price was
isNow = what the price is now

The straight lines mean "absolute value" - that means you take the positive answer of whatever's between the lines, even if it turns out negative. We don't care about the negative in this case because we just want to know how the change in price compares to the original price. The direction of the change doesn't matter.

Anyways, sub the appropriate values into the equation @P0sitr0n provided and you'll have your answer!

Answer 4

1.36/1.02 = increase.

Answer 5

Answer 6

Answer 8

hmm..
First find the difference between the original cost (1.02) and the new cost (1.36)
So 1.36 - 1.02 = ?

Answer 9

0.34

Answer 10

yep :)
Now to find the ratio of the INCREASE (0.34) to the original price (1.02) as a fraction would mean that :
0.34 (increase) / 1.02 (original)

Answer 11

0.33

Answer 12

yep :) and what does that equal to as a fraction? (In lowest terms)

Answer 13

1/3

Answer 14
