Final answer:
To convert the decimal 1.2 to a percent, you multiply it by 100 which gives you 120%. This can also be done by writing 1.2 as a fraction and converting it to have a denominator of 100, yielding the same result of 120%.
Step-by-step explanation:
To convert a decimal to a percent, you can follow a simple two-step process. Firstly, write the decimal as a fraction. Second, if the fraction does not have a denominator of 100, convert it to an equivalent fraction that does. Once you have a fraction with a denominator of 100, you can easily write it as a percent. Let us look at the provided decimal, 1.2.
Step 1: Write 1.2 as a fraction. This is simply done as 1.2/1.
Step 2: To convert this fraction to have a denominator of 100, multiply both the numerator and the denominator by 100. Hence, (1.2/1) × (100/100) = 120/100.
Now that the fraction has a denominator of 100, it can be written as 120%. Therefore, the decimal 1.2 converts to 120 percent.
To check your math, you can also simply multiply the decimal by 100. Moving the decimal point two places to the right, as in 1.2 × 100, also gives us 120.
