Question

Find two decimal fractions whose sum is 0.9 and difference is 0.2.​

Answer 1

Answer:

0.55 and 0.35

Step-by-step explanation:

let us assume a and b are 2 decimal numbers.

from the question we have a+b=0.9 and a-b=0.2

so on solving above equations we get a=0.55 and on substitution we get value of b as 0.35

So the 2 numbers are 0.55 and 0.35
