Question

THE SUM OF 2 RATIONAL NUMBERS IS -
$- \frac{ 4}{21}$
IF ONE OF THEM IS
$- \frac{3}{14}$
FIND THE OTHER ONE​

Answer 1

Answer:

Ok

Step-by-step explanation:

-4/21+(-3/21)

= - 4/21-3/21

= - 7/21

= - 1/3

Answer 2

Step-by-step explanation:

Given that ,

the sum of two rational numbers= -4/21

one of the number = -3/14

Let the other number be x

-3/14+x= -4/21

By transposing -3/14 to right side

x=3/14 - 4/21

Lcm =42

3/14=3/14×3/3=9/42

-4/21= -4/21×2/2=8/42

x=(9-8)/42

x=1/42

Therefore,the other number is 1/42

Prove:

1/42+(-3/14)

=1/42-3/14

Lcm=42

1/42=1/42×1/1=1/42

-3/14=-3/14×3/3= -9/42

1/42-9/42=(1-9)/42

= -8/42= -4/21
