Question

You use 4 gallons of water on 30 plants in your garden. At that rate, how much water

will it take to water 45 plants?

Answer 1

6 gallons

Explanation:

`Assuming\ that\ it\ will\ take\ x\ gallons\ waters`

`to\ water\ 45\ plants.`

`4:30=x:45`

`30x=4* 45`

`30x=18`°

`x=180/ 3\\ x=6`

`\left\{If\right.\ a:b=c:d,\ then\ ad=\left.\ bc\right\}`

I hope this helps you

Answer 2

6 gallons

Explanation:

30-----------4

45------------x

30x = 45x4

30x=180

x=6

A shortcut:

45 is ( 30+ half of 30)

( 4 + half of 4) = 4+2 =6
