Math percentage problems can often be confusing since they can have many variations. Whether you need to find the percentage of a number or what percentage a number is of another, each type of problem fortunately follows a set formula to make it simpler.
一个数的20%等于这个数的1/5,令n为这个数,1/5n=12,两边同时乘以5,得到n=60.n的30%等于3/(10)n=3/(10)*60=3*6=18,故B正确.故选B.20% of a number is equal to 1/5 of that number. Let n= the number 1/5n=12 Multiply both sides by 5n=6030% of n is equal to 3/(10)n=3/...
