1. ErinWeeks

2. ErinWeeks

A. 5/8 B. 2/5 C. 3/8 D. 3/5

3. ErinWeeks

I thought it was D but i got it wrong

4. Hero

Hint: $\frac{\text{no. of unshaded squares}}{\text{total squares}}$

5. ErinWeeks

40 / 64?

6. Hero

Yes, now reduce that

7. ErinWeeks

i got A 5/8

8. Hero

Good job. At least there's one student here that's teachable.

9. ErinWeeks

lol thank you so much i was doing it wrong i was dividing the shaded over the unshaded!

10. Hero

I only needed to give you one hint. Some students, I give two, three, four hints, and they still don't have a clue.

11. ErinWeeks

12. ErinWeeks

13. Hero
