Step-by-step explanation:
i could be wrong on c tho
You need to divide 2/5 and 3/4. First, you need to do "Keep Change Flip". We do this by keeping 2/5 the same, changing the division sign to a multiplication sign and flipping 3/4 to make 4/3. Lastly, you add them up and get your answer.
2/5 ÷ 3/4
2/5 X 4/3 = 8/15
The answer is 5x/2 because all you have to do is add 3x + 2x too make 5x and take 4-2 which is 2 and since it can't be simplified any more, just do 5x/2. Hope this helped! :)
