Question

Use the numbers in the multiplication equation 45 x 1/9 =5 to write a division equation involving division by a fraction.

Answer 1

ANSWER
$45 = \frac{5}{ \frac{1}{9} }$

Or
$\frac{1}{9} = \frac{5}{45}$

EXPLANATION


The given multiplication equation is

$45\times \frac{1}{9} = 5$

To write a division equation, we divide both sides of the equation by
$\frac{1}{9}$
to obtain,



$\frac{45 \times \frac{1}{9} }{ \frac{1}{9} } = \frac{5}{ \frac{1}{9} }$


This simplifies to

$45 = \frac{5}{ \frac{1}{9} }$

This is one of the division equations.


We could have also divided both side of the given equation by 45 to get another division equation,

$\frac{45 \times \frac{1}{9} }{45} = \frac{5}{45}$



This gives us,


$\frac{1}{9} = \frac{5}{45}$
