Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 10}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{ \frac{4}{x} = \frac{28}{70}} [/tex]
Do cross multiplication
[tex] \longrightarrow{ \sf{28x = 4 \times 70}}[/tex]
Multiply the numbers: 4 and 70
[tex] \longrightarrow{ \sf{28x = 280}}[/tex]
Divide both sides by 28
[tex] \longrightarrow{ \sf{ \frac{28x}{28} = \frac{280}{28}}} [/tex]
Calculate
[tex] \longrightarrow{ \sf{x = 10}}[/tex]
