Question

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

Answer 1

Answer:

7). 1

8). 3

9). 1

Step-by-step explanation:

7). $[3\div (2\times 1)]\frac{2}{3}$

  $=[3\div 2]\frac{2}{3}$

  $=\frac{3}{2}\times \frac{2}{3}$

  $=1$

8). $2(3\times 2-5)+3\times \frac{1}{3}$

  $=2(6-5)+\frac{3}{3}$

  $=2(6-5)+1$

  $=2+1$

  = 3

9). $6\times \frac{1}{6}+5(12\div 4-3)$

  $=6\times \frac{1}{6}+5(\frac{12}{4}-3 )$

  $=1+5(3-3)$

  = 1
