有关what percent,OG12有很多例子。选项应该要带百分号的。
PS-60. A glass was filled with 10 ounces of water, and 0.01 ounce of the water evaporated each day during a 20-day period. What percent of the original amount of water evaporated during this period? (A) 0.002% (B) 0.02% (C) 0.2% (D) 2% (E) 20%
Arithmetic Percents Since 0.01 ounce of water evaporated each day for 20 days, a total of 20(0.01) = 0.2 ounce evaporated. Then, to fi nd the percent of the original amount of water that evaporated, divide the amount that evaporated by the original amount and multiply by 100 to convert the decimal to a percent. Thus, 0.2/10 × 100 = 0.02 × 100 or 2%. The correct answer is D. |
