Question

Find the sum of these questions​

Answer 1

Step-by-step explanation:

(i) 1/5 + 3/5

Since their denominators are same, we can add the numbers in numerator first and then divide....

=> (1+3)/5 = 4/5

(ii) 3/-7 & 2/7

Here, 3/-7 can be also written as -3/7

and also their denominators are same, add the numbers in numerator and then divide...

=> -3+2/7 = -1/7

I hope you got it!

Answer 2

$\large{ \pmb{ \sf 1st \: question }}$

• Find the Sum of $\sf\dfrac{1}{5}$ and $\sf\dfrac{3}{5}$

$\large{ \pmb{ \sf 1st \: Answer }}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: : \implies \dfrac{1}{5} + \dfrac{3}{5} = \red{\dfrac{4 }{5} }$

$\large{ \pmb{ \sf 2nd \: question }}$

• find the sum of $\sf\dfrac{3}{-7}$ and $\sf\dfrac{2}{7}$

$\large{ \pmb{ \sf 2nd \: Answer }}$

• 3/-7 can be written as -3/7

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: : \implies \dfrac{ - 3}{7} + \dfrac{2}{7} = \red{\dfrac{ - 1 }{7} }$

I hope it's helpful :)
