Write in decimal form. Seven and three tenths
The Correct Answer and Explanation is:
Correct Answer: 7.3
Explanation:
To write “seven and three tenths” in decimal form, we need to understand the meaning of each part of the phrase.
- “Seven” is the whole number part. In numerals, that is simply 7.
- “Three tenths” refers to the fractional part. A tenth is one part out of ten equal parts. The fraction for three tenths is written as 3/10. In decimal form, 3/10 = 0.3. This is because the digit 3 is in the tenths place, which is the first digit to the right of the decimal point.
When you combine the whole number and the fractional part, you place the decimal point between them. So, seven and three tenths becomes:
7 + 0.3 = 7.3
This decimal has a 7 in the units place and a 3 in the tenths place. Let’s look at the place value chart to understand this clearly:
| Place | Value |
|---|---|
| Units | 7 |
| Tenths | 3 |
This means the number is composed of:
- 7 ones (or units)
- 3 tenths
Let’s consider a real-life example: Suppose you have $7 and 30 cents. That’s the same as $7.30, but when talking about tenths, we only look up to the first decimal place, so $7.30 can also be read as seven and three tenths, or simply 7.3.
In conclusion, writing numbers in decimal form involves identifying the whole number part and converting the fractional part into decimal format. In this case, “seven and three tenths” is simply written as 7.3.
