Question

the value of -3/10 + 13/-10 + 25/10 is ​

Answer 1

Answer:

Value of expression is $\frac{-3}{10} +\frac{13}{-10} + \frac{25}{10}$ , is  $\frac{9}{10}$ .

Step-by-step explanation:

To find : value of given expression .

Given : $\frac{-3}{10} +\frac{13}{-10} + \frac{25}{10}$

Solution :

• To solve the given expression of rational numbers , we first check denominators of fraction whether they are same or not . If not same then we equalize them by taking LCM .
• But here denominators are same , therefore we directly solve expression by taking denominator common and performing arithmetic operations of  numerators .

          $\frac{-3}{10} +\frac{13}{-10} + \frac{25}{10} \\\\= \frac{-3}{10}+ \frac{-13}{10} + \frac{25}{10} \\\\= \frac{-3 -13 + 25}{10} \\\\= \frac{9}{10}$

Answer 2

$= \frac{ - 3}{10} + \frac{ - 13}{10} + \frac{25}{10}$

$= \frac{ - 3 - 13 + 25}{10}$

$= \frac{ - 16 + 25}{10}$

$= \frac{9}{10}$
