sugar-free gum contains 40% less calories than regular gum. If a piece of regular gum contains 40 calories, how may calories does a piece of sugar-free gum contain?

Answer 1

im pretty sure this is right...

first, you make the percent into a decimal.

and then you multiple them.

so here's your work:

.40

x40

-------

16

im not a geek,i just know a little mathh (:

Answer 2

If something is 40% smaller, you just subtract 40%.

So 40% of 40 calories is 16: you do this by multiplying 40 by 0.4.

The answer would be 40 - 16 = 24

A shorter way would just be to multiply by 40 by 0.6, since that's 1-0.4.

Answer 3

do 40/100 *40 = 16 because it is 40 percent of 40 calories.

40-16=24 calories

Answer 4

40x[60/100] =24 calories

60% because it is 40% less

Answer 5

40*.4=16

40-16=24 calories

Answer 6

24 calories.

you just multiply 40 with .60 since thats the amount that will be left.

Answer 7

24 calories

40 *.4=16

40-16=24

Answer 8

40% of 40 is 16  so..........40-16=24...sugar-free gum has 24 calories

Answer 9

The answer is "The piece of sugar-free gum contains 24 calories"

Answer 10

36 calories
