Answer:
25%
Explanation:
"twice" means two times.
"twice the value of 1/8" is
2 × 1/8
(to multiply a whole number times a fraction, multiply the big number × the top number)
2 × 1/ 8 is 2/8
2/8 is 1/4.
1/4 = .25 = 25%
Since the answer is a percent, change 1/4 to a decimal, .25, change the decimal to a percent.
Or you could change 1/4 to 25/100. Percent means "per hundred" 25/100 is 25%.
