Question

1. [(7x8) - (18/3) + (-2) x (-4)] x (6/3)
2. (1/2 +1/4) divide by 4/9

Answer 1

1. $[(7\times8)-($ $18\over3$ $)$ $+$ $(-2)\times(-4)$ $]$ $\times$ $($ $6\over 3$ $)$

$=(56-6-2\times 4) \times 2$

$=(56-6+8) \times 2$

$=(50+8)\times 2$

$58\times 2 =116$

2.$($ $1\over 2$ $+$ $1\over 4$ $)$ $\div$ $4\over9$

$1\over 2$ $+$ $1\over 4$ $=$ $3\over4$

$3\over 4$ $\times$ $9\over 4$ $=$ $27\over 16$

$=1$ $11\over 16$
