Final answer:
To solve the problem, multiply 3.12 by 1,000, which is the same as moving the decimal point 3 places to the right. The answer is 3,120.
Step-by-step explanation:
To solve the given problem, we need to multiply 3.12 by 1,000. Multiplying any number by 1,000 is the same as moving the decimal point 3 places to the right.
Calculating 3.12 x 1,000:
There are two approaches to solve this:
1. Direct Multiplication:
3.12 x 1,000 = 3.12 x 10³ = 3.12 x 1000 = 3120.0
2. Decomposing the problem:
3.12 x 1,000 = (3 + 0.12) x (1000) = 3 x 1000 + 0.12 x 1000 = 3000 + 120 = 3120.0
Both methods lead to the same answer: 3120.0
So, 3.12 × 1,000 = 3,120.
