First; let's find out the sum of -3/10 and 5/8

LCM of 8 and 10 = 40

Making the terms like,

\frac{ - 12}{40} \: + \: \frac{25}{40}

Step-2 Find out the sum of 4/15 and 2/-5

Remember - Denominator can never have a negative sign. So, the fraction now, will be, -2/5

LCM of 15 and 5 = 15

Making the terms like,

\frac{4}{15} \: + \: \frac{ - 6}{15}

Answer 2

Step by Step Explanation:

Given: $\frac{15}{8} - \frac{23}{16}$

To Find: The solution to the above equation.

For calculation of the above equation:

We are given an equation $\frac{15}{8} - \frac{23}{16}$

In order to subtract it, we need to find LCM

The LCM is 16.

⇒$\frac{15}{8} - \frac{23}{16}$

⇒ $\frac{15}{8} x \frac{2}{2} - \frac{23}{16}$

⇒ $\frac{30}{16} - \frac{23}{16}$

Now we have the LCM, we will subtract both the equations,

⇒ $\frac{30-23}{16}$

⇒ $\frac{7}{16}$ = $0.4$

The answer is $\frac{7}{16}$ or $0.4.$
