If 𝑥 % of 200 is equal to y% of 250, then what is the ratio 𝑦 : 𝑥 ?
Explanation
Explanation
Equating the two expressions and simplifying gives:
x cdot 200 = y cdot 250 Rightarrow frac{y}{x} = frac{200}{250} = frac{4}{5}
Rightarrow y : x = 4 : 5 x ⋅ 200 = y ⋅ 250 ⇒ y /x = 200 / 250 = 4 /5 ⇒ y : x = 4 : 5
