Decimal Form: 0.025

Explanation:

Answer 2

`22 \frac12` acres

Explanation:

We need to find 3/4 of 30.

Method 1

30 by 3/4:

`\implies 30 * \frac34=(30)/(1)* \frac34= (30*3)/(1 *4)=(90)/(4)=22 \frac12`

Method 2

Divide 30 by 4: 30 ÷ 4 =
`(15)/(2)`

Multiply the result by 3:
`(15)/(2)` x 3 =
`(45)/(2)` =
`22 \frac12`
