Question

Find the Whole number ratio form of $12\frac{3}{4}:11\frac{1}{2}:17\frac{1}{6}$ [3 Marks]

Answer 1

$12\frac{3}{4}=\frac{51}{4}$

$11\frac{1}{2}=\frac{23}{2}$

$17\frac{1}{6}=\frac{103}{6}$

So,. $12\frac{3}{4}:11\frac{1}{2}:17\frac{1}{6}=\frac{51}{4}:\frac{23}{2}:\frac{103}{6}$ [1 Mark]

LCM of denominators of 4,2 and 6 is 12 [1 Mark]

Multiply the each term of the ratio by LCM . we get...

$\frac{51}{4}\times 12:\frac{23}{2}\times 12:\frac{103}{6}\times 12$

= 153 : 138 : 206 [1 Mark]
