Question

5/13+15/26+-10/39 find the sum​

Answer 1

• As per the data given in the question, we have to find the value of the expression.

        Given data:-$\frac{5}{13}+\frac{15}{26}+\frac{-10}{39}.$

        To find:-  value of the given expression.

        Solution:-

• We will take the LCM of the denominators, and make denominators the same.
• We will Convert the given fractions to equivalent fractions with the denominator as the LCM.
• Adding the numerators over the denominators.

        Therefore,

       $=\frac{5}{13}+\frac{15}{26}+\frac{-10}{39}.\\=\frac{5\times6+15\times3-10\times2}{78}\\=\frac{30+45-20}{78}\\=\frac{75-20}{78}\\=\frac{55}{78}.$

       Hence, the value will be $\frac{55}{78}.$

Answer 2

Answer:

$\frac{55}{78}$

Step-by-step explanation:

• Given expression: $\frac{5}{13}+\frac{15}{26}-\frac{10}{39}$

• As per the data given in the question, we need to find the sum of the given fractions.

$\frac{5}{13}+\frac{15}{26}-\frac{10}{39}$

• To add the above fractions, we need to find the LCM of denominators

• LCM of $13,26,39=78$

$=\frac{5\times6+15\times3-10\times2}{78}$

$=\frac{30+45-20}{78}$

$=\frac{55}{78}$

Hence, the value of $\frac{5}{13}+\frac{15}{26}-\frac{10}{39}$ is $\frac{55}{78}$.
