Question

find the sum of 2.3 (bar on 3)and 4.15 (bar on 15)

Answer 1

$2.3 = 2 + \frac{3}{9} = \frac{21}{9} \\ 4.15 = 4 + \frac{15}{99} = \frac{396}{99} \\ now \: add \: both \: the \: numbers \\ \frac{21}{9} + \frac{396}{99} \\ = \frac{627}{99} = 19$

Answer 2

Answer:

$2.\bar{3}+4.\bar{15}=6.\bar{48}$

Step-by-step explanation:

Given : Numbers 2.3(bar on 3) and 4.15 (bar on 15)

To find : The sum of two numbers.

Solution :

Bar means the number repeat itself,

$2.\bar{3}=2.333333......$

$4.\bar{15}=4.15151515......$

Now, we add these term

$2.\bar{3}+4.\bar{15}$

$=2.333333.....+4.15151515....$

$=6.484848.......$

$=6.\bar{48}$

Therefore, $2.\bar{3}+4.\bar{15}=6.\bar{48}$
