Question

What should be added to [3/4+1/3] to get 2 ? with explanation

Answer 1

$\huge{answer}$

1/2 + 1/3 + 1/5 + x = 3

Multiply all terms by 30 to get rid of the denominators:

30/2 + 30/3 + 30/5 + 30x = 30*3

15 + 10 + 6 + 30x = 90

31 + 30x = 90

30x = 49

x = 49/30

Substitute for x in the original equation to prove this:

1/2 + 1/3 + 1/5 + x = 30

x = 49/30

1/2 + 1/3 + 1/5 + 49/30 = 30

Multiply all terms by 30 to get rid of the denominators:

30* 1/2 + 30 * 1/3 + 30*1/5 + 30* 49/30 = 90

30/2 + 30/3 + 30/5 + 49 = 90

15 + 10 + 6 + 49 = 90

25 + 6 + 49 = 90

31 + 49 = 90

90 = 90

Since x = 49/30 you need to add 49/30 to (1/2 + 1/3 + 1/5) to get 3.

Answer 2

Answer:

9/12

Step-by-step explanation:

3/4 + 1/3 + ? = 2

= 3/4 + 1/3

= 15/12 (1 [3/12])

So, 2 - 15/12

= 9/12
