Answer 1

1.There would be 15 quarters :)
2.I don't know this answer I will tell you if I solve it

Answer 2

x = total number of people

4/9x = 280

5/9 of total = adults

4/7 adults = women

You can do the math.

Answer 3

1. How many quarters are there in 3 1/4?
3*4 + 1 = 13 not 15

2. There were 280 children at a fair. 4/9 of the people were children and the rest were adults. 3/7 of the adults were men. How many women were there?

(4/9) p = 280 so p = 630 people total
1 - 4/9 = 5/9
(5/9) 630 = 350 = adults
1 - 3/7 = 4/7
(4/7) 350 =200 women

Answer 4

1 whole → 4 quarters
3 wholes → 3 × 4 quarters = 12 quarters 12 + 1 = 13
There are 13 quarters.
