Question

the sum of 3 rational numbers is 11/16. if 2 of the rational numbers are -3/4 and 7/8 . find the third rational number​

Answer 1

minus 3 by 4 + 7 by 8 + X = 11/16. - 6 + 7 by 8 + X equal to 11 by 16 .X equals to 11 by 16 - 1 by 8 x equals to 11 - 2 by 16 thus answer is 9/16

Answer 2

Answer:

Step-by-step explanation:

I tried my level best hope it's correct

Sum of three rational numbers is 11 / 5.

two rational numbers is is -3 /4, 7 /

8

Let x be third rational number then,

7/8+(-3/4)+x=11/16

7/8-3/4+x=11/16

7/8-3/4*2/2+x=11/6. (*is symbol of multiply)

7/8-6/8+x=11/16

1/8+x=11/16

X=11/16-1/8

X=11/16-1/8*2/2

X=11/16-2/16

X=9/16
