Hi there!

These can all be solved by using the cross product method :

1. $\frac{40}{8} = \frac{45}{x}$

(45 × 8) ÷ 40 = x

360 ÷ 40 = x

9 = x

→ ANSWER : $\frac{40}{8} = \frac{45}{9}$

2. $\frac{42}{14} = \frac{x}{5}$

(5 × 42) ÷ 14 = x

210 ÷ 14 = x

15 = x

→ ANSWER : $\frac{42}{14} = \frac{15}{5}$

3. $\frac{x}{2} = \frac{56}{8}$

(2 × 56) ÷ 8 = x

112 ÷ 8 = x

14 = x

→ ANSWER : $\frac{14}{2} = \frac{56}{8}$

4. $\frac{x}{4} = \frac{26}{13}$

(4 × 26) ÷ 13 = x

104 ÷ 13 = x

8 = x

→ ANSWER : $\frac{8}{4} = \frac{26}{13}$

5. $\frac{4}{32} = \frac{9}{x}$

(9 × 32) ÷ 4 = x

288 ÷ 4 = x

72 = x

→ ANSWER : $\frac{4}{32} = \frac{9}{72}$

6. $\frac{9}{3} = \frac{x}{4}$

(4 × 9) ÷ 3 = x

36 ÷ 3 = x

12 = x

→ ANSWER : $\frac{9}{3} = \frac{12}{4}$

7. $\frac{3}{x} = \frac{2}{1.25}$

(3 × 1.25) ÷ 2 = x

3.75 ÷ 2 = x

1.875 = x

→ ANSWER : $\frac{3}{1.875} = \frac{2}{1.25}$

There you go! I really hope this helped, if there's anything just let me know! :)
