Question

the difference between two rational no. is 7/8. if one no. is -1/3. what is the other no.?

Answer 1

Answer:

Step-by-step explanation:

→ difference between two rational no. is 7/8.

→ if one no. is -1/3

→ let other number be x

→ -1/3 - x = 7/8

→ -x = 7/8+1/3

→  -x = 7*3/8*3 + 1*8/3*8

→  -x = 21/24+8/24

→ -x=29/24

→ x =  -29/24

Answer 2

Difference of two numbers = 7/8

Known number = -1/3

Let the unknown number be x

Difference of two numbers = 7/8

So, equation formed :

$x - ( - \frac{1}{3} ) = \frac{7}{8}$

$x + \frac{1}{3} = \frac{7}{8}$

$x = \frac{7}{8} - \frac{1}{3}$

Since Least Common Multiple of 8,3 is 24

$x = \frac{7 \times 3}{8 \times 3} - \frac{1 \times 8}{3 \times 8}$

$x = \frac{21}{24} - \frac{8}{24}$

$x = \frac{13}{24}$
