Question

What number should be added to -5/8 so as get -3/2?

Answer 1

Step-by-step explanation:

Let us consider x

−1+x=

7

5

Solving for x,

x=

7

5

−(−1)=

7

5

+1

By taking LCM of 2 and 8 is 8

7

5+(1×7)

=

7

5+7

=

7

12

x=

7

12

∴

7

12

should be added to −1 to get

7

5

.

Answer 2

Step-by-step explanation:

Let Consider x,

$\frac{ - 5}{8} + x = \frac{ - 3}{2}$

Solving x,

$x = \frac{ - 3}{2} - \frac{ - 5}{8}$

By Taking LCM Of 2 and 8 is 8.

$\frac{( - 3 \times 4) - ( - 5 \times 1)}{8} = \frac{ - 12 - ( - 5)}{8} = \frac{ - 12 + 5}{8} = \frac{ - 7}{8}$

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

$\frac{ - 7}{8} should \: \: be \: \: added \: \: to \: \: \frac{ - 5}{8} to \: \: get \: \: \frac{ - 3}{2}$
