Answer 1

Answer:

1. $266\dfrac{2}{3}\%$

2. $400\%$

Step-by-step explanation:

1. Fraction $\frac{1}{4}$ is 100%, then

$\dfrac{1}{4} - 100\%\\ \\\dfrac{2}{3} - x\%$

Write a proportion:

$\dfrac{\frac{1}{4}}{\frac{2}{3}}=\dfrac{100}{x}$

Cross multiply:

$\dfrac{1}{4}x=\dfrac{2}{3}\cdot 100\\ \\x=4\cdot \dfrac{2}{3}\cdot 100\\ \\x=\dfrac{800}{3}\\ \\x=266\dfrac{2}{3}\%$

2. Fraction $\frac{1}{6}$ is 100%, then

$\dfrac{1}{6} - 100\%\\ \\\dfrac{2}{3} - x\%$

Write a proportion:

$\dfrac{\frac{1}{6}}{\frac{2}{3}}=\dfrac{100}{x}$

Cross multiply:

$\dfrac{1}{6}x=\dfrac{2}{3}\cdot 100\\ \\x=6\cdot \dfrac{2}{3}\cdot 100\\ \\x=\dfrac{1,200}{3}\\ \\x=400\%$
