Question

what should be added to 40/7 to get 12?​

Answer 1

Answer:

44/7

Step-by-step explanation:

40/7+44/7

= 84/7

=12

x+40/7=12

x=12-40/7

x=84/7-40/7

x=44/7

Answer 2

Given - Number: 40/7

Sum: 12

To find - Number to be added to get the sum

Solution - Let the number be added to get the sum be x. Thus, representing the given information in a mathematical form we get -

40/7 + x = 12

Taking L.C.M., we get -

(40 + 7*x)/7= 12

Taking 7 to Right Hand Side and multiplying with 12. Now, the new mathematical expression will be -

40 + 7x = 12*7

40 + 7x = 84

7x = 84 - 40

7x = 44

x = 44/7

Thus, the number to add to 40/7 to get the sum 12 is 44/7.
