Question

Add the following rational numbers :
$\frac{3}{5} and - 2$
​

Answer 1

Answer:

-7/5

Step-by-step explanation:

(3/5 )+(-2)

(3/5)-2

(3/5)-10/5. because we multiply both num and denom with 5 to equalize

3-10/5

-7/5

Answer 2

Answer:

$\huge- \frac{7}{5}$

Step-by-step explanation:

Given

First Rational Number = 3/5

Second Rational Number = -2

And

We have to add both rational numbers

$= > \frac{3}{5} + ( - 2) \\ = > \frac{3}{5} - \frac{2}{1} \\ \bold{On \: taking \: L.C.M.} \\ = > \frac{3 - 2 \times 5}{5} \\ = > \frac{3 - 10}{5} \\ = > - \frac{ 7}{5}$

Some very simple steps which to be care during solving these type of Addition or subtraction

• Sign matters a lot so it's better to write first each rational number in brackets.
• And we have to put the sign what is being asked in the question between the number brackets.
• Then we have to multiply the sign having inside brackets with outside sign.
• Then Take L.C.M. and solve. Finally get your answer.
