Write the following fraction as a decimal:
First let's write the simple fraction as a decimal fraction:
Since the fraction is divisible by 10, we'll can move the decimal point one place to the left to obtain:
2.2
Write the following fraction as a decimal:
\( \frac{5}{100}= \)
Dividing by 10 makes numbers smaller, so the decimal moves left! Think of it this way: 22 ÷ 10 = 2.2, which is much smaller than 22.
You'll need to do long division instead! The decimal point shortcut only works for powers of 10 (10, 100, 1000, etc.).
Count the zeros in the denominator! For 10 (one zero), move 1 place left. For 100 (two zeros), move 2 places left.
That's called an improper fraction! It converts to a decimal greater than 1, like 2.2. This is perfectly normal and correct.
Yes! But learning the decimal point method helps you understand place value and makes you faster at mental math without a calculator.
