Question

how 0.15+0.15=0.3 cause i got the answer 30 but the calculater is showing 0.3

Answer 1

Answer: 0.3

Explanation:

0.15 + 0.15 gives you 0.30...

But the zeroes which are on the right does not add a value. So if zero gets cancelled (0.30) the value stays the same (0.3).

Answer 2

Answer:

because

0.15

+ 0.15

0.30

then if you write this value in rational form then you get

=>. 30 =>. 3 => 0.3

100 10

this is why the calculator shows 0.3
