N = number
....................................

<u>n </u>+ 18 = n
4

<u>n </u>= n - 18
4

Cross Multiply

4 * ( n - 18 ) = n
4n - 72 = n
4n - n = 72
3n = 72
n =<u> 72 </u>
       3
n = 24

We can turn this into an equation. 
if x stands for the number you are looking for, then

18 + 1/4 x = x

we can solve this equation

18 + 1/4 x = x
subtract 1/4x from both sides
18 = 3/4 x
divide both sides by 3/4
24 = x

15/10 to a mixed number
tensa zangetsu [6.8K]
First, we have to find how many times 10 goes into 15.

We can divide 15 by 10, and we will see that 10 goes into 15 1 whole time, with 5/10 left over.

Now, we can simplify!

In order to simplify, we have to find the GCF (greatest common factor) of 5 and 10. Let's list out the factors (the numbers that can be divided into 5 and 10)

1*5

1*10
2*5

The largest factor, as we can see, is 5! Let's dicide 5/10 by 5.

5/5=1
10/5=2

So, 5/10 simplifies to 1/2, and, if we bring down the whole number we found before, 15/10 is equal to 1 and 1/2! :)

We can check this answer by multiplying the whole number, 1, by the denominator, (the bottom number of a fraction) 2, and adding the numerator, (the top number of a fraction), 1.

1*2=2
2+1=3

Keep the denominator as 2.

The improper fraction is 3/2, which is equivalent to 15/10 (multiply 3/2 by 5 to see)!

So, our answer is 1 1/2.

I hope I helped! :)
