To solve the problem of multiplying 1.52 by 10, we follow these simple steps:
Let's perform these steps:
Starting with 1.52, when we shift the decimal point one place to the right, we move from 1.52 to 15.2. This is because multiplying by 10 increases the value by one order of magnitude.
Thus, the product of is . Therefore, the correct answer choice is .
\( \text{0}.07\times10= \)
Moving the decimal point is actually the same as regular multiplication but much faster! When you multiply by 10, you're making each digit 10 times bigger, which shifts everything one place left - that's why the decimal moves right.
Every whole number has an invisible decimal point at the end! For example, 15 is really 15.0, so (decimal moves right).
The pattern continues! Multiply by 100: move decimal 2 places right. Multiply by 1000: move 3 places right. The number of zeros = number of places to move!
Very rarely! Just remember: multiplying by 10 makes numbers bigger, so 1.52 should become something bigger like 15.2, not smaller like 0.152.
Add zeros! If you need to move , move 2 places right: 1.5 → 15. → 150. The final zero is necessary!
