Divisibility Rules
- A number is divisible by 2 if its last digit is even: 0, 2, 4, 6, or 8.
- A number is divisible by 3 if the sum of its digits results in a number that can be divided by 3 without a remainder.
- A number is divisible by 4 if the number formed by its last two digits can be divided by 4.
- A number is divisible by 5 if its last digit is either 0 or 5.
- A number is divisible by 6 if it meets the criteria for both 2 and 3.
- A number is divisible by 8 if the number created by its last three digits is divisible by 8.
- A number is divisible by 9 if the sum of its digits is divisible by 9.
- A number is divisible by 10 if its last digit is 0.
Problem 29: Product Calculation
- Given the expression 115/5 x 5/3.
- Simplifying 115/5 results in 23.
- The other fraction remains 5/3.
- Multiplying the simplified results leads to 23 x 5/3 = 115/3.
- Final fraction 115/3 is in its lowest term, as 115 and 3 have no common factors.
