Algebra Difficulty 1.1 Junior Find the answer Canada

If the numbers $2\frac{3}{4}$ ,
2.3, $2\frac{1}{4}$ , 2.45, and $2\frac{9}{10}$ were arranged from least to
greatest, the middle number would be

Pick one

Solution

Expressing the given fractions as decimals, we get $2\frac34=2.75$ , $2\frac14=2.25$ , and $2\frac{9}{10}=2.9$ . Arranging from least
to greatest, we get $2.25$ , $2.3$ , $2.45$ , $2.75$ , $2.9$ or $2\frac14$ , $2.3$ , $2.45$ , $2\frac34$ , $2\frac{9}{10}$ . The middle number is $2.45$ .
