What is the original price if saidhari and she paid $75 and it was 1/4 off the price

1 answer:

4 0

Let's set the original price as x.

1/4 off the original price would be

x-1/4x=3/4x

Set it equal to 75

3/4x=75
3x=300
x=100

The original price was $100.

Hope this helps!

I know the answer to 255.5 ➗ 7 but how would you write it out.. (I'm not smart)

Ainat [17]

There are several ways such as
255 $\frac{1}{2}$ / 7

First put it in the decimal equation
Since there is a decimal in the number being divided(255.5), you move the decimal so that it is a whole number(2555) but since you move the decimal place once, you do the same to the 7 so that it is now 70. So now it's 2555/70 which looks like 365 but then, you have to place the decimal value so that it is now 36.5
This is what you use to divide as shown.
