Order Decimals and Fractions

In an earlier lesson, we compared two decimals and determined which was larger. To compare a decimal to a fraction, we will first convert the fraction to a decimal and then compare the decimals.

example

Order (38)(38) and (0.4)(0.4) using << or >.>.

Solution

(38)(38)  (0.4)(0.4)
Convert 38 to a decimal. (0.375)  (0.4)
Compare 0.375 to 0.4 0.375<0.4
Rewrite with the original fraction. 38<0.4

When ordering negative numbers, remember that larger numbers are to the right on the number line and any positive number is greater than any negative number.

example

Order (0.5) and (34) using < or >.
