This problem Is an example of geometrica progression. The formula
for the sum of geometric progression is:
S = a[(r^n)-1] / (r – 1)
Where s is the sum
a is the first term = 1
r is the common ratio = 2 ( because it doubles every year
n is the number of terms = (19) since the first term is when
he was born which he still 0
s = S = 1[(2^19)-1] / (2 – 1)
s = $524,287

Answer:
Step-by-step explanation:
Step 1: Find the total fraction of raisins he gave to his brothers
=
Step 2: Find the lowest common multiple(Lcm) of 6 and 4
Lcm of 6 and 4 = 12
Step 3: Add the fractions
= 
= 
Step 4: To find the fraction that he kept, you will subtract the total fractions he gave his brothers from 1.
Final answer
The fraction that he kept = 
Hope this helps but I think there is a 1/4 or a 25% chance of somebody winning a prize.
Answer:
I think it is 160 x2 so you would probably divide 160 by x2 which would 144
