Video Solution

Solution Steps

00:00 Choose the appropriate sign
00:08 Convert decimal number to fraction
00:18 Reduce as much as possible
00:21 Remember to divide both numerator and denominator
00:37 Multiply the fraction by the second denominator to find the common denominator
00:44 Make sure to multiply numerator by numerator and denominator by denominator
00:50 Use the same method for the second fraction
00:55 Now let's compare the fractions
01:01 And this is the solution to the question

Step-by-Step Solution

First, let's convert 0.6 to a simple fraction.

Since there is only one digit after the decimal point, the number is divided by 10 as follows:

0.6=610 0.6=\frac{6}{10}

Let's reduce the fraction:

6:210:2=35 \frac{6:2}{10:2}=\frac{3}{5}

Now we have two simple fractions with different denominators.

To compare them, note that the smallest common denominator between them is 15.

We'll multiply each one to reach the common denominator as follows:

23×55=1015 \frac{2}{3}\times\frac{5}{5}=\frac{10}{15}

35×33=915 \frac{3}{5}\times\frac{3}{3}=\frac{9}{15}

Now we can compare the two fractions and see that:

\frac{10}{15}>\frac{9}{15}
