765 / 9 = 85
9*100 = 900 but this is too much
900 - 765 = 135
9 goes into 135 15 times (9*10=90 which leaves 45 which is 9*5 so 5+10) so you minus 15 from the 100 that made 900
so 100 - 15 = 85
Set up a proportion
3 coins:8 notes and then the other one 24 coins : x (unknown notes)
they have a relationship so we can set them equal to each other.
3/8=24/x cross multiply: 8 * 24 = 192
Now divide that by 3: 192/3 = 64
So there are 64 notes in the bag
They each get 14 cents,
A quarter = 25c
A nickel = 5c
A dime = 10c
2 pennies = 2c
25 + 5 + 10 + 2 = 42c
42 divided by 3 is 14 cents
So Willie, Donald and Maya get 14 cents each
hi
4 entries are 24 so one entry is 24/4 = 6
so 7 friends pay 6*7 = 42
I think the answer is around 1.4 as you need to multiply the area by 1/9 after finding the real area.
