Answer 1

5 3/5:3 1/2=5 1/4 : x

28/5:7/2=21/4:х

28/5*2/7=21/4:х

х=21/4:8/5

х=21/4*5/8

х=105/32

х=3 9/32

Answer 2

$5 \frac{3}{5} \div 3 \frac{1}{2} = 5 \frac{1}{4} \div x \\ x = 3 \frac{1}{2} \times 5 \frac{1}{4} \div 5 \frac{3}{5} \\ x = \frac{7}{2} \times \frac{21}{4} \div \frac{28}{5} \\ x = \frac{7}{2} \times \frac{21}{4} \times \frac{5}{28} \\ x = \frac{105}{32} = 3 \frac{9}{32}$
