Question

Evaluate each expression. Name the property used in each step.

Answer 1

7). 1

8). 3

9). 1

Explanation:

7).
`[3/ (2* 1)](2)/(3)`

`=[3/ 2](2)/(3)`

`=(3)/(2)* (2)/(3)`

`=1`

8).
`2(3* 2-5)+3* (1)/(3)`

`=2(6-5)+(3)/(3)`

`=2(6-5)+1`

`=2+1`

= 3

9).
`6* (1)/(6)+5(12/ 4-3)`

`=6* (1)/(6)+5((12)/(4)-3 )`

`=1+5(3-3)`

= 1
