Ariana plans to use $260 less than three-fourths of savings to buy a car. If the purchase price of the car is 9,340, how much do

tangare [24]

She has $12,488 in savings

Step-by-step explanation:

Ariana plans to use $260 less than three-fourths of savings to buy a car.

If the purchase price of the car is 9,340, we need to find how much

she has in savings

To find the savings

Assume that she has $x in savings
Write an equation of x
Solve the equation to find x

∵ She has $x in savings

∵ She plans to use $260 less than three-fourths of savings

- Three-fourths means $\frac{3}{4}$ and less than means subtract

∴ She plans to use $\frac{3}{4}$ x - 26

∵ The purchase price of the car is 9,340

- Equate the expression of x by 9,340

∴ $\frac{3}{4}$ x - 26 = 9,340

Now let us solve the equation

∵ $\frac{3}{4}$ x - 26 = 9,340

- Add 26 to both sides

∴ $\frac{3}{4}$ x = 9,366

- Divide both sides by $\frac{3}{4}$

∴ x = $12,488

She has $12,488 in savings

put the fraction in least to greatest denomenator then put them in order please help me 1/2 3/4 1/5 7/10 please help me

DiKsa [7]

Working with fractions, you'll need to find the least common denominator (LCD). In this case, the LCD is 20.

Rewriting the four given numbers to the LCD, you would get:

10/20, 15/20, 4/20, and 14/20.

Now, you just organize it from least to greatest as:

4/20 < 10/20 < 14/20 < 15/20.

In other words, it is:

1/5 < 1/2 < 7/10 < 3/4.
