Identifying divisors and multiples, prime and composite numbers, and using divisibility rules for 2, 3, 5, 9, and 10.
If one quantity increases, the other increases at the same rate. For example, if a value increases 7 times , its proportional counterpart also increases 7 times . Percentage Problems: Finding a whole from a part. Identifying divisors and multiples
Example: If represents 19% of a total, the total ( ) is calculated as: prime and composite numbers
