Find the Number of Tenths in 1.3: Decimal Place Value Practice

Q: How do I remember which place is tenths?

The tenths place is always the first digit right after the decimal point. Just like: ones | decimal point | tenths | hundredths | thousandths.

Q: What if the number was 1.30 instead?

Still 3 tenths! The zero in hundredths place doesn't change the tenths value. 1.30 = 1.3 = 3 tenths.

Q: Can I convert this to a fraction to check?

Yes! 1.3 = $ 1\frac{3}{10} $ which clearly shows 3 tenths in the fractional part.

Understand the problem

Determine the number of tenths in the following number:

1.3

Step-by-step solution

To solve this problem, we'll follow these steps:

Step 1: Understand the problem of finding the number of tenths in 1.3.
Step 2: Note that the decimal number 1.3 is composed of the whole number 1 and the decimal fraction 0.3.
Step 3: Recognize that the tenths place is the first digit after the decimal point.

Now, let's work through each step:

Step 1: The problem asks us to count the number of tenths in the decimal number 1.3. This involves understanding the place value of each digit.

Step 2: In the decimal 1.3, the digit '1' represents the whole number and does not contribute to the count of tenths. The digit '3' is in the tenths place.

Step 3: Since the digit '3' is in the tenths place, it denotes 3 tenths or the fraction $\frac{3}{10}$ .

Therefore, the number of tenths in 1.3 is $3$ .

Common Mistakes

Avoid these frequent errors

Counting all digits instead of just tenths
Don't count both 1 and 3 to get 13 tenths = completely wrong answer! The whole number part doesn't contribute to tenths count. Always focus only on the digit in the tenths place (first position after decimal).

FAQ

Everything you need to know about this question

Why isn't the answer 13 since I see both 1 and 3?

The 1 is in the ones place (whole number), not the tenths place! Only the digit 3 is in the tenths position. Think of 1.3 as 1 whole + 3 tenths.

How do I remember which place is tenths?

The tenths place is always the first digit right after the decimal point. Just like: ones | decimal point | tenths | hundredths | thousandths.

What if the number was 1.30 instead?

Still 3 tenths! The zero in hundredths place doesn't change the tenths value. 1.30 = 1.3 = 3 tenths.

Can I convert this to a fraction to check?

Yes! 1.3 = $1\frac{3}{10}$ which clearly shows 3 tenths in the fractional part.

What about bigger numbers like 25.7?

Same rule applies! In 25.7, the 7 is in the tenths place, so there are 7 tenths regardless of how big the whole number part is.
