Question 3

Given expression:

$\sf \left(\dfrac{-8}{9} \times \dfrac{1}{-5}\right)+\left(\dfrac{-8}{9} \times \dfrac{-7}{11}\right)$

Both parentheses share a common term.

To factor out a common term: ab + ac = a(b + c)

$\textsf{Factor out the common term }\dfrac{-8}{9}$

$\sf \implies\dfrac{-8}{9} \times \left(\dfrac{1}{-5}+\dfrac{-7}{11}\right)$

Question 4

To calculate the amount of money Rajni had to begin with, sum the three amounts she spent:

$\sf \implies total=10\frac14+25\frac34+16\frac12$

As $\sf a\frac{b}{c}=a+\frac{b}{c}$ , then:

$\sf \implies 10+\frac14+25+\frac34+16+\frac12$

Collect and sum the whole numbers:

$\sf \implies (10+25+16)+\frac14+\frac34+\frac12$

$\sf \implies 51+\frac14+\frac34+\frac12$

As $\sf \frac14+\frac34=\frac44=1$ , then

$\sf \implies 51+1+\frac12$

$\sf \implies 52+\frac12$

$\sf \implies 52\frac12$
