If y is k% of x, what % of x is k3y ?
Correct Answer:
A: k3
Explanation:
If y is k% of x, what % of x is k3y ? Correct Answer k3 We can solve this problem using algebra.If y is k% of x, then we can write:y = k/100 × xMultiplying both sides by k², we get:k²y = k²/100 × kx = k³/100 × xSo k³y is (k³/100) times x. To express this as a percentage of x, we can multiply by 100 and get:k³y = (k³/100) × x = k³%Therefore, k³y is k³% of x.
