Sagot :
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 [tex]\frac{90}{100} \times x[/tex]
then;
[tex]\frac{90}{100}x =12[/tex]
or
[tex]\frac{9}{10}x=12[/tex]
Multiply both sides by [tex]\frac{10}{9}[/tex] ,
[tex]\frac{9}{10}x \times \frac{10}{9} =12 \times \frac{10}{9}[/tex]
Simplify:
[tex]x =\frac{120}{9} = \frac{40}{3} = 13.33333...[/tex]
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 = [tex]\frac{90}{100}\times 13.34[/tex]
12 = [tex]0.9 \times 13.34[/tex]
12=12.00 [true]
