3. Create a Venn diagram or Table with numbers for: A group of 80 students were asked if they were taking science or art.
10 were taking neither, 50 were taking science, 30 were taking art.

10 students were taking science and art at the same time.

Step-by-step explanation:

Given that a group of 80 students were asked if they were taking science or art, of which 10 were taking neither, 50 were taking science, and 30 were taking art, to determine how many students take both science and art, the following calculation must be done:

80 - 10 = 70

50 - 30 - 70 = X

80 - 70 = X

10 = X

Therefore, 10 students were taking science and art at the same time.

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
