Answer 2

Answer:

i. $a = 0.64$

ii. $b = 13.44$

Step-by-step explanation:

i.  $\frac{a}{3} = \frac{1.5}{7}$

CROSS - MULTIPLYING ...

$7a = 1.5$ × $7$

$a = \frac{4.5}{7}$

∴ $a = 0.64$

ii.  $\frac{1.5}{4.2} = \frac{4.8}{b}$

CROSS MULTIPLYING ...

$1.5b = 4.8$ × $4.2$

$1.5b = 20.16$

∴ $b = 13.44$
