What fraction of 20 is 18?
Vera_Pavlovna [14]

Remark

You have to read this carefully to know what way to write it.

One way you could write it would be

20 * x = 18 where x is  the fraction. Now all you need do is divide.

Divide both sides by 20

20/20 * x = 18/20

\text{x = } \dfrac{18}{20}

But you should reduce this fraction. The way to do that is to factor 18 and 20 into primes.

18: 2 * 3 * 3

20: 2 * 2 *5

Cancel out the Highest common factor or 2.

You are left with

\text{x = } \dfrac{18}{20} =\dfrac{2*3*3}{2*2*5}=\dfrac{3*3}{2*5} = \dfrac{9}{10} <<<< Answer

Answer:

All expressions are correct

Step-by-step explanation:

9z+7z = 16 z

We need to find an expression ( or expressions ) that are equal to 16z

6z+3z+ 7z = 16z  Correct

z+8z+7z = 16z   Correct

z*16 = 16z  Correct

21z+ -5z = 16z  Correct
