Question

what no. should be added to-2/3 to get 7/11​

Answer 1

Answer:

−19

Step-by-step explanation:

To Find :What number should be added to \frac{7}{12}127 to get\frac{4}{15}154 ?

Solution:

Let the number be x

A number should be added to \frac{7}{12}127 to get\frac{4}{15}154

So, x+\frac{7}{12}=\frac{4}{15}x+127=154

x=\frac{4}{15}-\frac{7}{12}x=154−127

Take LCM of 15 and 12 is 60

x=\frac{4}{15}-\frac{7}{12}x=154−127

x=\frac{16-35}{60}x=6016−35

x=\frac{-19}{60}x=60−19

Hence \frac{-19}{60}60−19 should be added to \frac{7}{12}127 to get\frac{4}{15}154

Answer 2

Answer:

Let the number added be X.

Then,

A/q

X + (-2/3) = 7/11

X -2/3 = 7/11

X = 7/11 +2/3

X = 21 +22/33

X = 43/33.

Hence, 43/33 is the number.
