349/10= 34.9

b) 120+30+8=158

so, I will divide 158 by 10

158/10= 1.58

Thank you .

Answer 2

a) 300 + 40 + 6 + 3/10

$= \frac{346}{1} + \frac{3}{10}$

LCM of 1 and 10 = 10

$= ( \frac{346}{1} \times \frac{10}{10}) + \frac{3}{10}$

$= \frac{(3460 + 3)}{10}$

$= \frac{3463}{10}$

$\huge\mathcal\pink{ = 346.3}$

b) 120 + 30 + 8/100

$= \frac{150}{1} + \frac{8}{100}$

LCM of 1 and 100 = 100

$= ( \frac{150}{1} \times \frac{100}{100}) + \frac{8}{100}$

$= \frac{(15000 + 8)}{100}$

$= \frac{15008}{100}$

$\huge\mathcal\pink{ = 150.08}$
