Answer:
x = 4
x = 3
x = 10
x = 3
x = 16
x = 35
Step-by-step explanation:
[tex]\frac{x}{5} :\frac{8}{10}[/tex]
x · 10 = 5 · 8
10x = 40
10x ÷ 10 = 40 ÷ 10
x = 4
[tex]\frac{8}{12} :\frac{2}{x}[/tex]
x · 8 = 12 · 2
8x = 24
8x ÷ 8 = 24 ÷ 8
x = 3
[tex]\frac{15}{3} :\frac{x}{2}[/tex]
x · 3 = 15 · 2
3x = 30
3x ÷ 3 = 30 ÷ 3
x = 10
[tex]\frac{x}{6}:\frac{6}{12}[/tex]
x · 12 = 6 · 6
12x = 36
12x ÷ 12 = 36 ÷ 12
x = 3
[tex]\frac{x}{8} :\frac{4}{2}[/tex]
x · 2 = 8 · 4
2x = 32
2x ÷ 2 = 32 ÷ 2
x = 16
[tex]\frac{10}{2} :\frac{x}{7}[/tex]
x · 2 = 10 · 7
2x = 70
2x ÷ 2 = 70 ÷ 2
x = 35
