Question

8. What should be added to 7/15 to get -3/8 ?​

Answer 1

Answer:

$x = \frac{ - 101}{120}$

Step-by-step explanation:

Let the no. to be added be x

$\frac{7}{15} + x = \frac{ - 3}{8}$

We can also write it as

$x = \frac{ - 3}{8} - \frac{ 7}{15}$

Finding the LCM of 15 and 8, which is 120

$x = \frac{ - 3 \times 15}{8 \times 15} + \frac{ - 7 \times 8}{15 \times 8}$

$x = \frac{ - 45 - 56}{120}$

$x = \frac{ - 101}{120}$

That's your answer.
