Question

The sum of two rational numbers is 44/55.If one number is 2/15,find the other number

Answer 1

Answer:

2/3

Step-by-step explanation:

Given:

Sum of the two Rational Numbers = 44/55

One of the numbers = 2/15

To find:

The second number.

Solution:

Let the second number be x.

∴ x + 2/15 = 44/55

x = 44/55 - 2/15

Since the denominators are different, we will take the L.C.M. of the denominators.

Here, the L.C.M. of 15 and 55 is 165

Hence, 2/15 = 22/165 and 44/55 = 132/165

Hence, (132 - 22)/ 165 = 110/165

= 10/15

= 2/3

Answer 2

Answer:

It is said that the sum of two rational numbers is 44/55.

i.e., x+x=44/55

If one of those numbers or x is 2/15..

i.e., 2/15+x=44/55

Then we should find the other number or x.

So,

2/15+x=44/55

x=44/55-2/15. (side change sign change)

x=132-22/165

x=110/165

x=22/33

So the other number is 22/33.

Now you can add 22/33 and 2/15 to see if the sum of these two rational numbers is 44/55 or not.

=22/33+2/15

=110+22/165

=132/165

=44/55

So this is your answer dear friend.

Hope this will help you.
