$\bf \cfrac{9!9!}{10!7!}\implies \cfrac{~~\begin{matrix} 9! \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~9\cdot 8\cdot ~~\begin{matrix} 7! \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}{10\cdot ~~\begin{matrix} 9! \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~\cdot ~~\begin{matrix} 7! \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}\implies \cfrac{72}{10}\implies \cfrac{36}{5}\implies 7.2$

A pitcher of water contains 1/4 of water. The water is poured equally into 5 glasses. How many liters of water are in each glass

IRINA_888 [86]

Hey there!

To solve this, divide the numbers 1/4 and 5 . . .

1/4 = 1/4

5 = 5/1

1 x 1 = 1

4 x 5 = 20

= 1/20

1/20 is already in it's simplest form, so it doesn't need to be simplified.

There are 1/20 liters of water in each glass.

Hope this helps you.
Have a great day!
