Question

find the sum -5/10+3/16+7/16​

Answer 1

Answer:

The Correct Answer is -35/8

Step-by-step explanation:

-5/10 + 3/16 + 7/16

-5/10 + 10/16

Now taking the LCM,

= ( -400 + 50 ) / 80

= ( -350 ) / 80

= -35 / 8

Answer 2

To find : sum of   $\frac{-5}{10} + \frac{3}{16} + \frac{7}{16}$

Solution :

• To find the sum of    $\frac{-5}{10} + \frac{3}{16} + \frac{7}{16}$  we need to make denominators equal .
• to equalize denominators we take LCM of denominators .
• LCM = 80
• Now, multiplying numerator by same as multiplied by denominator to get LCM 80.  

     ⇒           $\frac{-40}{80} + \frac{15}{80} + \frac{35}{80}$

• Now , by combining denominator and adding numerator we get required answer.

                       $= \frac{-40 + 15 + 35}{80}$

                       $= \frac{10}{80}$

                       $= \frac{1}{8}$

     Hence , $\frac{1}{8}$ is the sum of given rational numbers.
