Challenge Question 7:

4 9/11 + 3 7/8

we add wholes and convert 9,8,7 to bar numbers.

7  1(1) /11 + 1(3)/1(2)

We multiply crosswise and add to get numerator.

7  1(3)2 + 1(23) / 1(12)

We multiply denominators to get denominators

7   2(51) / 1(12)

7  149/88

8  61/88

We can use bar numbers in fractions. But I found it little complicated to use them. Looking forward to see different approaches
