Question

what is the sum of -9/10+22/15
please say the answer ​

Answer 1

Answer:

-9/10+22/15 = 17/30

Step-by-step explanation:

First, we have to find LCM

LCM = 30

Then, we have to make the denominators equal:

-9/10 multiplied by 3 equals -27/30

22/15 multiplied by 2 equals 44/30

Now, we have to add both of them:

-27      44      17

------ + ------ = ------

30       30      30

Therfore, the answer is 17/30

Answer 2

According to the question it is given that,

We have to find the sum of

$\frac{-9}{10} +\frac{22}{15}$

For that first, we need t find its lowest common denominator:

$=>\frac{(-9\times 3)}{10\times 3)} +\frac{(22\times 2)}{(15\times 2)}$

Multiplying both the numerator and denominator we get:

$=>\frac{-27}{30} +\frac{44}{30}$

By combining both the fractions we get:

$=>\frac{(-27+44)}{30}$

Now by adding both the numerator:

$=>\frac{17}{30}$

Hence, the sum of $\frac{-9}{10} +\frac{22}{15}$ is $\frac{17}{30}.$
