Question

What should be added to 7 2/3 to get 21?

Answer 1

Answer:

40/3

Step-by-step explanation:

7 2/3 + x = 21 (.°. 7 2/3 = 23/3)

23/3 + x = 21

x = 21 - 23/3

x = 21 × 3 - 23/3

x = 63 - 23/3

x = 40/3

Thus, 40/3 should be added to 7 2/3 to get 21

FOR VERIFICATION ONLY:

23/3 + x = 21

23/3 + 40/3 = 21

23 + 40/3 = 21

63/3 = 21

21 = 21

Hence, L.H.S = R.H.S
