Question

I need the answers for this one as well!​

Answer 1

For the sake of showing work I will replace the empty space with an x like so...

$\frac{9}{10} =\frac{90}{x}$

To find out what x is you must cross multiply (aka butterfly)

***Image of this step is attached below

9*x = 10*90

9x = 900

Next divide 9 to both sides to finish isolating x. Since 9 is being multiplied by x, division (the opposite of multiplication) will cancel 9 out (in this case it will make 9 one) from the left side and bring it over to the right side.

9x ÷ 9 = 900 ÷ 9

1x = 100

x = 100

To make these fractions equivalent the empty spot must be 100

$\frac{9}{10} = \frac{90}{100}$

Hope this helped!
