Is this correct??
a)
Before
Apples - u+200
Pears - u
After
Apples - 3/4 + 150
Pears - 5/7 + 170
3/4 + 150 = 5/7 + 170
3/4 - 5/7 = 170 - 150
21/28 - 20/28 = 20
1u/28 = 20
20×28=560
560+200=760
b)
560×5÷7=400

Yup, your final answers are correct but for the "after" column, the number of pears left should be 5/7u instead of 5/7u+170. Hope this helps!
