Answer:

1.
266(2)/(3)\%

2.
400\%

Explanation:

1. Fraction
(1)/(4) is 100%, then


(1)/(4) - 100\%\\ \\(2)/(3) - x\%

Write a proportion:


((1)/(4))/((2)/(3))=(100)/(x)

Cross multiply:


(1)/(4)x=(2)/(3)\cdot 100\\ \\x=4\cdot (2)/(3)\cdot 100\\ \\x=(800)/(3)\\ \\x=266(2)/(3)\%

2. Fraction
(1)/(6) is 100%, then


(1)/(6) - 100\%\\ \\(2)/(3) - x\%

Write a proportion:


((1)/(6))/((2)/(3))=(100)/(x)

Cross multiply:


(1)/(6)x=(2)/(3)\cdot 100\\ \\x=6\cdot (2)/(3)\cdot 100\\ \\x=(1,200)/(3)\\ \\x=400\%
