<u>
</u>
<u>Step-by-step explanation:</u>
To solve a complex fraction like
, take LCM of both the terms separately first to get:
= 
and

Now combine and divide these terms to get:

The term
in both the denominators will be cancelled out by each other and you will be left with:

Therefore, the expression
is equivalent to the given complex fraction.
Answer:
4
Step-by-step explanation:
You need to try out all the numbers.
lets start with 4
if there where 4 red marbles then there would be 9 times as many marbles
so 4 x 9 = 36
Now we add and see if the sum is 40
36 + 4 = 40
We got it on the first try
You can use the same method on more problems like these.
Hope this helps :)
If we are trying to find x then it is 21
all you have to do is set them equal to each other
so (4x+3)=87
