2 x 6300 = 12,600
The actual answer is 12,508.
greater
When one factor is less than one, the product will be less than the other factor.
When they have a common prime factor. When their GCF is greater than 1.
It means to express a number as the product of its factors. Factors are either composite numbers or prime numbers (except that 0 and 1 are neither prime nor composite).
The product will be greater than either of the factors.
9X60
You cannot since the suggested method will always lead to an underestimate.
9 x 500 = 4500 and 9 x 600 = 5400, so you know the answer will be close to halfway between those two numbers. The actual answer is 4860.
Compatible numbers would be easier. Rounding gives you 14 x 47. Compatible numbers could be 13 x 50 which would be closer to the actual product.
The terms (factors) used in multiplication are the multiplicand (the factor being multiplied), the multiplier (the factor that the multiplicand is multiplied by) and the product (the answer, or results of the multiplication). Any time either of the factors is greater than the other by at least one, the product will always be greater than the largest factor.
In the equation 4 x 9 = 36, the product (36) is greater (larger) than each factor (4 and 9).
greater
The product is less than the other factor. For example: 0.5 x 6 = 3. 3 is less than the factor that is greater than 1 (which is 6).
Their product.
The answer would be an overestimate.
70 x 20 = 1400
When one factor is less than one, the product will be less than the other factor.
