Question

Find the difference of the following

Answer 1

Step-by-step explanation:

1) 3-4/9 = 27/9 - 4/9 = 23/9

2) 20 1/2 - 19 1/3= 41/2 - 58/3 = 123/6 - 116/6

= 7/6 = 1 1/6

Answer 2

Step-by-step explanation: A:-

3 - $\frac{4}{9}$ =

$\frac{3}{1} - \frac{4}{9}$ =

LCM of 1 and 9 = 9

∴$\frac{3*9}{9} - \frac{4}{9}$

$\frac{27}{9} - \frac{4}{9}$

$\frac{23}{9}$

Step-by-step explanation: B:-

$\frac{20*2+1}{2}$ - $\frac{19*3+1}{3}$

$\frac{41}{2}$ - $\frac{58}{3}$

LCM of 2 and 3 = 6

$\frac{41*3}{6} - \frac{58*2}{6}$

$\frac{123}{6} - \frac{116}{6}$

$\frac{7}{6}$ (OR)$1\frac{1}{6}$
