问题 If 20% of x equals 16, then x =_____
选项
答案80
解析 Set up a proportion. You are given that 20% of x is equal to 16, and you want to find the value of x. The proportion will look like this:
16/x=20/100
After cross-multiplying, you are left with 20x = 1,600. After dividing both sides by 20, you have the answer: x = 80.
