The decimal point separates the place values that are whole values on the left from the place values that are fractional parts on the right, as illustrated in the table below.

Explain Guided Practice Now we will have a race to see who can write improper fractions as mixed numbers and mixed numbers as improper fractions correctly in the fastest time. Explain the use of 0 as a placeholder in the tenths place since both the tenths and hundredths places have to be filled to show 0.

Our decimal system lets us write. This is going to be equal to 0. Introduction 10 minutes Engage students in a discussion about any nicknames they may have.

Explain that fractions and decimals are different names for the same value. The numerator of the fraction will always be placed on the inside, as the dividend, and the denominator of the fraction will always be placed on the outside, as the divisor.

The digit five remains in the tenths' column so these values are all equal to five-tenths. So let's actually input it into the answer box now. Now, we can write our decimal as a fraction. You should double-check our result by expanding the binary representation. The last 4 problems ask students to place values on a number line.

We will continue this process until we get a zero as our decimal part or until we recognize an infinite repeating pattern. We then will discuss the terms terminating, repeating, decimals and repetend.

At this point we can conclude that when a remainder value repeats we will have a repeating decimal otherwise the decimal will terminate. You see that there are 3 place values filled, so you know that the thousandths place value is filled. Notice that we had to add a zero after the 6 in order to move the decimal place.

In order to convert a decimal into a percent, we need to move the decimal point two places to the right. The numerator is the decimal number we see, so in this example the numerator would be I'll do another turn-and-talk around the essential question.

And we know it's going to involve some decimals over here, because 27 is larger than 19, and it doesn't divide perfectly. A common fraction is a numeral which represents a rational number.To convert a percent to a decimal, first remove the percent symbol, then move the decimal point two places to the left.

Look at the Example 1 below. Example 1: Write each percent as a decimal. Conversions. From Percent to Decimal.

To convert from percent to decimal: divide byand remove the "%" sign. The easiest way to divide by is to move the decimal point 2 places to the left.

Writing decimals in words should not be hard if you understood my lesson about reading and writing whole numbers Do not try to study this lesson before getting a good solid understanding of how read and write whole numbers. To call a decimal a "terminating" decimal means that "it ends", unlike, say, the decimal for, which goes on forever.

A non-terminating AND NON-REPEATING decimal CANNOT be converted to a fraction, because it is an " irrational " (non-fractional) number. To write a fraction as a decimal, you just need to divide - in this case, divide 1 by 27 to get Let's try another one.

Write 4^-2 as a fraction and as a decimal. Convert Fractions to Decimals. The simplest method is to use a calculator. Find a number you can multiply by the bottom of the fraction to make it 10, ororor any 1 followed by 0s.

is nearly 1, so let us write down with the decimal point 3 spaces from the right (because 1, has 3 zeros).
