[tex]\boxed{ \ 90 \ is \ \frac{1}{10} \ of \ 900 \ }[/tex]

Further explanation

The question can be rewritten to [tex]\boxed{ \ 90 \ is \ \frac{1}{10} \ of \ N \ }[/tex]

This is a question about equations with one variable. We have to solve this calculation to obtain the value of N. Our task is to isolate the variable N alone at the end of the process on one side of the equation until the variable will be equal to a value on the opposite side.

Let's arrange it into an equation, i.e., [tex]\boxed{ \ 90 \ = \ \frac{1}{10} \times \ N \ }[/tex]

Turn this equation over so that the position of variable N is on the left side.

[tex]\boxed{ \ N \times \frac{1}{10} = 90 \ }[/tex]

Both sides are multiplied by 10 to isolate N on the left side.

[tex]\boxed{ \ N \times \frac{1}{10} \times 10 = 90 \times 10 \ }[/tex]

N = 900

Therefore, we have determined the number that was asked.

Hence, [tex]\boxed{ \ 90 \ is \ \frac{1}{10} \ of \ 900 \ }[/tex]

Note:

The important thing to carry out is how to manipulate both sides of the equation with the algebraic properties of equality such as:

  • Adding,  
  • Subtracting,  
  • Multiplying, and/or  
  • Dividing both sides of the equation with a similar number.

And, last but not least, the commutative property of multiplication [tex]\boxed{ \ a \times b = b \times a \ }[/tex]
