Question

arrange in descending order: 3½ , 2½ , 8¼ ​

Answer 1

Answer:

Improper fractions :

$3 \frac{1}{2} = \frac{7}{2} \\ \\ 2 \frac{1}{2} = \frac{5}{2} \\ \\ 8 \frac{1}{4} = \frac{33}{4}$

Now LCM is 4

$\frac{7 \times 2}{2 \times 2} = \frac{14}{4}$

$\frac{5 \times 2}{2 \times 2} = \frac{10}{4}$

Now, compare

$\frac{33}{4} > \frac{14}{4} > \frac{10}{4}$

$8\frac{1}{4} > 3 \frac{1}{2} > 2\frac{1}{2}$
