You can make every number up to 15 using only 8, 4, 2, and 1 .
If you want to expand your horizons all the way to 18, you'll need the next one
in the same series. That's 16. Once you have that, you'll be able to make every
number up to 31 .

It is: 25/18 = 1 and 7/18 as a mixed number
2 x 32 = 18
2 x 32 = 18
2 dimes, 8 pennies, 1 dime 18 pennies
If a number is added to itself, it is twice that number → 18 ÷ 2 = 9 → 9 + 9 = 18
The only number that goes into 18 and 31 is 1.
18 is a composite number because a prime number can only be multiplied by 1 and itself. 18 can be multiplied by 9 and 2 also.
