To solve this problem, we will execute the following simple steps:
In-depth walkthrough:
Step 1: We start with the number 15.1.
Step 2: Since we multiply by 10, we shift the decimal point one place to the right.
Step 3: This changes 15.1 into 151.
Therefore, the solution to the problem, as reflected in the provided answer choices, is the number , which corresponds to choice 2.
\( \text{0}.07\times10= \)
Multiplying by 10 makes each digit ten times bigger, which moves it to the next place value position. The decimal point appears to 'move right' but really the digits are shifting left!
Every whole number has an invisible decimal point at the end! For example, 25 is really 25.0, so .
Yes! Move the decimal point two places right for ×100, three places right for ×1000. The number of zeros equals the number of places to move.
Add zeros as placeholders! If you have , move two places right: 1.5 → 15. → 150.
151 is a whole number (151 ones), while 15.1 is a decimal (15 ones and 1 tenth). Multiplying by 10 changed tenths into ones!
