My grandma keeps a bunch of hard candy in her purse. She ran across a kid who was sad because he scrapped his knee on the ground and gave him a quarter of the candy in her purse. Later she went to a church function and ate one third of what she had left. Then she went home. At the end of the day, what percent of the candy she started with, did she have left?

About 40%

Step-by-step explanation:

Think of the candy as a circle. You take away 25 percent of it. Then you take away about 34 percent. Then add 25+34 which equals about 60%. then subtract 60 percent from 100. Which is 40. So about 40% is your answer.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
