Thanks. But can explain further. Why blueberry left is 5/7-14/35 and last equation of 11/35 divide by 5/7? Dun understand, sorry too weak in fraction. Btw, teacher answer is 4/15. Is his answer wrong?
Think i understanding wrongly on 2/5 of tarts he had...
Let me redo...

Your teacher answer is correct, 4/15
I thought blueberry left was 2/5 of tarts he had at 1st.

To answer your queries, why last equation need to ÷ 5/7.
Questions asked for fraction of blueberry tarts was left
Fraction = blueberry left / blueberry at 1st
Therefore,
= blueberry left ÷ blueberry at 1st
= 4/21 ÷ 5/7
= 4/21 × 7/5
= 4/15
Hope this clarify your doubts.
If you have any parts need more explanation, let me know... Cheers.

Another tutor also misunderstood the question on 2/5 the number of tarts he had.
The question should write clearly.. like..
2/5 the number of tarts he had left. :)
