First find one third of the number 72. We can do this by either dividing 72 by 3, or by multiplying 72 by 1/3. I will divide 72 by 3.
72/3 = 24
We have completed half of the problem; one third of the number 72. Now the number Barbie is thinking of is twenty less than the number we just found, 24.
To solve this problem subtract 20 from one third of the number 72; 24.
24 - 20 = 4
The number that Barbie is thinking of is 4.
Answer:
number of gym members who prefer bicycling : 18/75*350 = 84
number of gym members who prefer exercise classes: 22/75*350 ≈ 103
number of gym members who prefer running on the treadmill: 15/75*350 = 70
number of gym members who prefer weight lifting: 20/75*350 ≈ 93
Step-by-step explanation:
GYM SURVEY RESULTS
Type Number of Members
Bicycling 18
Exercise Classes 22
Running on Treadmill 15
Weight Lifting 20
Total 75
Dear Joanna243, what do you mean by a "negative fraction decimal". You can't have a fraction and a decimal at the same time. I'll solve it anyway. Take 1/3 and do 1÷3 to get approximately 0.33, then you plug the -3 with 0.33 to get -3.33
It would be C because it is right
The ratio is 54:11
Divide 810 by 54 to see what you need to multoply by. Doing this gives you15
Now multiply 11 by 15 and you get 165. So 165 people out of 810 people are attending camp. Hope this helps
