Rosy waxes 2/3 of her car with 1/4 bottle of car wax. At this rate, what fraction of the bottle of car wax will Rosy use to wax her entire car?

Hey there! I'm happy to help!

We see that Rosy uses 1/4 of the bottle to wax 2/3 of the car.

We need to 1/3 more to wax the entire car.

1/3 is half of 2/3.

We used 1/4 bottle for 2/3 of the car.

Therefore, we need half of 1/4 bottle for 1/3 more of the car.

1/4×1/2=1/8

We add this to the original 1/4 to see the total amount we used to wax the entire car.

1/4+1/8=3/8

Therefore, Rosy will use 3/8 of the bottle of car wax to wax her entire car.

3/8 bottle

Step-by-step explanation:

We can use ratios to solve

2/3 car         1 car  

=

1/4 bottle     x bottles

Using cross products

2/3x = 1/4

Multiply each side by 3/2

3/2 * 2/3 x = 3/2 * 1/4

x = 3/8
