8/9 is the answer. Hope I helped!


Brainliest if satisfied




<span>Multiply both sides by 10. The goal is to move the decimal point to the next repeating portion (which is just one spot to the right) 




Now subtract the equation  from  to get 

 


 Combine like terms. Notice how the decimal portions cancel out. 


 Divide both sides by 9</span>

This process works to convert any numerical repeating patter into a rational number...

let x=0.888 then 10x=8.888 so getting the difference...

10x-x=8.888-0.888

9x=8

a family has two cars. the first car has a fuel efficiency of 20 miles per gallon of gas and the second has a fuel efficiency of
nikklg [1K]

Car A consumes 25 gallon and car B consumes 15 gallon.

Step-by-step explanation:

Given,

The fuel efficiency of car A = 20 miles per gallon.

The fuel efficiency of car B = 15 miles per gallon.

In a week, two cars went 725 miles and consumed 40 gallons.

To find the consumption of each car in that week.

Let,

Car A consumed x gallon

Car B consumed y gallon.

According to the problem,

x+y = 40 ----- (1)

20x+15y = 725

or, 4x+3y = 145 -------- (2)

From (1) we get, x = 40-y

Putting the value of x in (2) we get,

4(40-y)+3y = 145

or, 160-4y+3y = 145

or, -y = 145-160

or, y = 15

From (1) we get, x = 40-15 = 25

Hence,

Car A consumes 25 gallon and car B consumes 15 gallon.
