Final answer:
To write a number as a decimal, understand place value and divide the numerator by the denominator for fractions.
Step-by-step explanation:
To write a number as a decimal, you need to understand place value. Each place value represents a power of 10. For example, in the number 345.67, the 3 is in the hundreds place, the 4 is in the tens place, the 5 is in the ones place, the 6 is in the tenths place, and the 7 is in the hundredths place.
Let's take an example: to write the fraction 3/5 as a decimal, you divide the numerator (3) by the denominator (5). This gives you 0.6. So, 3/5 can be written as the decimal 0.6.
