Can someone help. Write a word problem about equal groups and act it out to solve
Alona [7]

Answer:

HOPE THAT MAY HELP YOU :)

Step-by-step explanation:

Equal groups are illustrations of using the same variable.

A word problem that uses equal group is:  

Christopher traveled a distance of 5 miles yesterday; he traveled a distance of 4 miles earlier today. Calculate the total distance traveled  

The only condition for equal groups is that:  

The units or variable must be the same  

For instance:

Add 5 miles and 4 miles ----- This represents distance

Remove 2 liters from 7 liters --- This represents volume

Add 5 hours and quarter of an hour -- This represents time

And so on.

In order to make a specific shade of green paint, a painter mixes 1 1/2 quarts of blue paint, 2 cups of green paint, and 1/2 gal
ella [17]

Answer:

Step-by-step explanation:

In order to make a specific shade of green paint, a painter mixes 1 1/2 quarts of blue paint. Converting 1.5 quarts to cup,

1 quart = 4 cups

1.5 quarts = 1.5 × 4 = 6 cups

She also used 1/2 gallon of white paint. Converting 0.5 gallons to cup,

0.0625 gallons = 1 cup

0.5 gallons = 0.5/0.0625 = 8 cups

This means that the ratio of cups of blue paint to green paint to white paint is 6: 2 :8

Total ratio = 6 +2 + 8 = 16

To make 100 cups of this shade of green,

Cups of blue paint needed = 6/16 × 100 = 37.5 cups

Cups of green paint needed = 2/16 × 100 = 12.5 cups

Cups of white paint needed = 8/16 × 100 = 50 cups

Convert 17⁄8 to a decimal, rounded to the nearest hundredth. A. 2.13 B. 2.44 C. 1.78 D. 1.14
11111nata11111 [884]
Hey there! :)

All you have to do is divide the numerator(top number) by the denominator(bottom number).

17 ÷ 8 = 2.125

Rounded to the nearest hundredth = 2 places after the decimal point.

After the 2 is a 5. If it's 5 or greater, you move it up by 1.

2 + 1 = 3

2.125 = 2.13

Your answer is A ⇒ 2.13

Hope this helps :)
