Change the fraction to a percent.
ziro4ka [17]
The fraction in the picture is  1/8 . 
That's equivalent to 12.5 %.
____________________________________

Maybe what you want is the whole mixed number changed to percent.

-- The  5  alone is  500% .

-- The  1/8  alone is  12.5% .

-- When you puttum together and addum up,

                 (5 + 1/8)  =  (500%  +  12.5%)  =  512.5%  .

A certain pickup truck gets 20mpg in the city and 28 mpg on the highway. If the driver drives 270 mi on 11 gal of gas, determine
Snezhnost [94]

Answer:

95 city and 175 highway miles.

Step-by-step explanation:

The driver gets 20 mpg in city, and 28 mpg on the highway.

An equation that could be written is

20x+28y=270

This equation accounts for the distance traveled.

x+y=11

This equotion accounts for how many gallons were driven.

Multiply the bottom equation by 20, so you can solve the set of equations.

20x+28y=270

20x+20y=220

subtract them

8y=50

y=6.25

now plug this back into x+y=11

x+6.25=11

x=4.75

Now 4.75×20=95 city miles and 6.25×28=175 highway miles.
