The best thing to do is to find 10%.
You can do this by dividing 12 by 9.
12/9= 1.333
Therefore, 10% is equal to 1.333
1.333*10= 13.33
Therefore, 12 is 90% of 13.33

Hope this helps :)

Answer:

Let the number be x.

Then, the statement become; "90% of x is 12".

90% of x is written as  \(\frac{90}{100} \times x\)

then;

\(\frac{90}{100}x =12\)

or

\(\frac{9}{10}x=12\)

Multiply both sides by \(\frac{10}{9}\) ,

\(\frac{9}{10}x \times \frac{10}{9} =12 \times \frac{10}{9}\)

Simplify:

\(x =\frac{120}{9} = \frac{40}{3} = 13.33333...\)

then the value of number x is 13.34 (nearest hundredths).

Therefore, 12 is 90% of 13.34.

Check:

12 = 90% of 13.34

12 = \(\frac{90}{100}\times 13.34\)

12 = \(0.9 \times 13.34\)

12=12.00                              [true]
