a banner requires 1 1/2 sections of plastic. How many banners can be made from 12 sections of plastics?

A.7 B.8 C.9 D.15

Well, in order to answer this question, we first need to figure out how many sections of plastic are needed for each banner. So, if a banner requires 1 1/2 sections of plastic, it means that each banner uses 1 section plus half of another section. Now, if we have 12 sections of plastic, we can divide that by 1 1/2 to find out how many banners we can make.

So, let's do the math! 12 divided by 1 1/2 is the same as 12 divided by 3/2, which can be rewritten as 12 multiplied by 2/3. Well, 12 times 2 is 24, and 24 divided by 3 is 8. Tada!

So, the answer is B. 8 banners can be made from 12 sections of plastics.

Now, go throw a party with all those banners!

To find the number of banners that can be made from 12 sections of plastic, divide the total number of sections by the number of sections required for each banner.

1 1/2 sections = 3/2 sections

Number of banners = 12 sections / (3/2 sections)

Dividing 12 by 3/2 is the same as multiplying 12 by the reciprocal of 3/2:

Number of banners = 12 sections * (2/3 sections)

Number of banners = 24/3 sections

Simplifying, we get:

Number of banners = 8

Therefore, the correct answer is B. 8

To solve this problem, we need to divide the total number of sections of plastic by the amount required for each banner.

The given information states that 1 1/2 sections of plastic are required for one banner. To make the calculation easier, we can convert this mixed number to an improper fraction.

1 1/2 is equal to (2 * 1 + 1)/2 = 3/2

Now, we have the number of sections required per banner, which is 3/2.

To find out how many banners can be made from 12 sections of plastic, we need to divide 12 by 3/2:

12 ÷ 3/2

To divide by a fraction, we need to multiply by its reciprocal:

12 × 2/3

Now, multiply the numerators (12 × 2) and the denominators (1 × 3):

24/3 = 8

Therefore, 8 banners can be made from 12 sections of plastic.

So, the correct answer is B. 8

12 / (3/2) = 12 * (2/3) = 24/3 = 8
