Question
In which of the following multiplications is the product less than 1? Can you find the answer without actually doing the multiplications? (a) 7 × 0.6 (b) 0.7 × 0.6 (c) 0.7 × 6 (d) 0.07 × 0.06
Answer

Yes, we can find the answer without actual multiplication, only by using decimal place values. Multiplying by a number greater than 1: The product is greater than the original number. Multiplying by a number between 0 and 1: The product is less than the original number. Multiplying two numbers between 0 and 1: The product will be less than both factors, and therefore definitely less than 1. (a) Greater than 1. (b) Less than 1. (c) Greater than 1. (d) Less than 1.
