Dawn has 5\6 yard of lace. She uses 4\5 of it on a dress and the rest on a jewel box. How much does she use on the jewel box

mr_godi [17]

Answer:

Jewelry box: 1/6 yard

Step-by-step explanation:

4/5 (not 4\5) of her 5/6 yard goes into a dress: (4/5)(5/6 yd) = 2/3 yard.

This is the same as 4/6 yard. The amount of lace remaining, to be used on a jewelry box, is 5/6 - 4/6, or 1/6 yard.

Suppose a car has a rating of 4.8 gallons per 100 miles. What is the miles-per-gallon rating of this car?

bezimeni [28]

Answer:

The miles-per-gallon rating of this car is 20.83.

Step-by-step explanation:

This question can be solved by a rule of three.

What is the miles-per-gallon rating of this car?

How many miles for 1 gallon?

4.8 gallons are used for 100 miles. So

4.8 gallons - 100 miles

1 gallon - x miles

$4.8x = 100$

$x = \frac{100}{4.8}$

$x = 20.83$

The miles-per-gallon rating of this car is 20.83.
