Question

what should be added to 8whole3upon7 to get 11whole11upon14?​

Answer 1

Answer:

10 ⁴/7 or 74/7

Step-by-step explanation:

8 ³/7 can be written as [(7*8) + 3]/7 = 59/7

11 ¹¹/14 can be written as [(14*11) + 11]/14 = 165/14

Let the number to be added to 8 ³/7 be x.

==> 8 ³/7 + x = 11 ¹¹/14

==> x = 11 ¹¹/14 - 8 ³/7

==> x = 165/14 - 59/7

165 - 59(2)

==> x = --------------------

14

165 - 118

==> x = --------------------

14

==> x = 148/14

==> x = 74/7

(OR)

==> x = 10 ⁴/7
