Question

If x = (-1)/3 y= 2/7 then (x+y) =​

Answer 1

Answer:

-1/21

Step-by-step explanation:

If x = ( -1/3 ) and y = 2/7 then replace the value.

(x+y)

= -1/3 + 2/7

=> LCM of 3 and 7 = 21

-1/3 ×7/7 = -7/21

2/7 × 3/3 = 6/21

-7+6/21

= -1/ 21

Answer is -1/21

My first Answer

Answer 2

Answer:

-1/3 + 2/7

Take LCM

LCM of 3 and 7 is 21.

in -1/3 we must bring denominator to 21

by 3×7=21.

we must do for numerator too

(-)×(+)=(-)

-1×7=-7

Similarly in 2/7

Bring Denominator to 21

by 7×3=21

We must do for numerator too

2×3=6

What we multiplied for denominator we must multiply for numerator.

We must bring Denominator equal to 21 here.

So,

-7/21 + 6/21

(-)+(+)=Value of greater value number that is -7 and subtract

-1/21
