Question

what number should be added to-5upon8 so to get -3upon2​

Answer 1

Answer:

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

Step-by-step explanation:

Given:

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

So, the number added = x

By solving the linear equation:

$x = \frac{ - 3}{2} + \frac{5}{8} \\ x = \frac{ - 3 \times 4 + 5}{8} \\ x = \frac{ - 12 + 5}{8 } \\ x = \frac{ - 7}{8}$

Hope it helps you!!

Answer 2

$\rm\purple{Let \:the\:missing\:no. \:be\:x\:}$

$\rm\green{According \:To\:The\:Question\:,}$

We have,

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

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

$\implies$$\frac{ - 12 + 5}{8} = \frac{ - 7}{8}$
