Provide the answers to questions from image. All questions are mathematical.

1. a) $$3/15 = 1/5$$;
2. b) $$6/10 = 3/5$$;
3. h) $$6/21 = 2/7$$;
4. i) $$1\frac{1}{2} = \frac{3}{2} = \frac{15}{10}$$, so the fraction to fill in is $$3/2$$
5. c) $$\frac{5}{3} = \frac{15}{9}$$
6. d) $$\frac{5}{1} = \frac{20}{4}$$
7. k) $$\frac{3}{5} = \frac{18}{30}$$
8. e) $$\frac{6}{8} = \frac{18}{24}$$
9. l) $$\frac{12}{100} = \frac{3}{25}$$
10. f) $$\frac{5}{3} = \frac{15}{9}$$
11. q) $$\frac{10}{7} = \frac{100}{70}$$
12. p) $$\frac{24}{15} = \frac{8}{5}$$
13. o) $$\frac{1}{3} = \frac{20}{60}$$
