Answer:
A = [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
given the ratios
25 : 75 = A : 4
expressing the ratios in fractional form
[tex]\frac{25}{75}[/tex] = [tex]\frac{A}{4}[/tex] ( cross multiply )
75A = 4 × 25 = 100 ( divide both sides by 75 )
A = [tex]\frac{100}{75}[/tex] = [tex]\frac{4}{3}[/tex]
