Question

Please tell me with solution very quick..​

Answer 1

Answer:

(-441)/72

Step-by-step explanation:

Firstly, we need to give (-9) a denominator, which is 1

So, the equation becomes:

11/18 x (-9)/1 + (-3)/4 x 5/6

Next, we need to sort them in brackets. Such as:

[11/18 x (-9)/1] + [(-3)/4 x 5/6]

Now, we multiply the numbers in the brackets.

Firstly, we will solve the first bracket.

[11/18 x (-9)/1]

= (-99)/18

Secondly, we will solve the second bracket.

[(-3)/4 x 5/6]

= (-15)/24

Now, according to the question, we have to add the products to get the answer. Such as:

(-99)/18 + (-15)/24

Since the denominators are not of the same value, we have to convert them. Like so:

LCM of 18 and 24 is 72

(-99)/18 x 4/4 = (-396)/72

and

(-15)/24 x 3/3 = (-45)/72

Now, we add to get the answer.

(-396)/72 + (-45)/72

= (-441)/72 (answer)
