Answer:
7/9 = 49/63
16/21 = 48/63
7/9 > 16/21
Explanation:
First, we need to notice the following:
9 x 7 = 63
21 x 3 = 63
So, to get a common denominator, we will multiply the first fraction by 7 and the second fraction by 3, then:
[tex]\begin{gathered} \frac{7}{9}=\frac{7\times7}{9\times7}=\frac{49}{63} \\ \frac{16}{21}=\frac{16\times3}{21\times3}=\frac{48}{63} \end{gathered}[/tex]
So, the first part of the answer is
7/9 = 49/63
16/21 = 48/63
Now, the number with a greater numerator will be the greater. Since 49 is greater than 48, we get
7/9 > 16/21
So, the answers are:
7/9 = 49/63
16/21 = 48/63
7/9 > 16/21
