9/20 because you can divide them in half but you can divide them any further.
The grandmother is 63 and the grandson is 15.
You must find numbers that multiply up to 945:
Ex:
45*21=495
135*7=495
63*15=495
P=6 - value .01
d=12 or 2*p - value .1
n=3 - value .05
q=12 or 4*n - value .25
Multiply each denomination's value by how many she had.
(6*.01)+(12*.1)+(3*.05)+(12*.25)
.06+1.20+.15+3.00
$4.41
7 times 7 = 49. Perfect square.
3 times 3 = 9. Perfect square.
15 times 15 = 225. Again, a perfect square.
The other two, 17 and 143, come out as decimals. So, your final answer would be 49, 7 and 225. Hope it helps! If you could vote my answer as the brainiest, that would be awesome! :)
Answer: 3.96 pints
Step-by-step explanation: if 3/5 is blue, then 2/5 has to be white (since 3/5 + 2/5 = 1). Multiply 9.9 by 2/5 to get 3.96 pints
