In how many ways can 4 blue flags 3 green flags and 2 flags be arranged

 C. 1.5 : 1

Step-by-step explanation:

First, convert both numbers to improper fractions.

6 1/2 converts to 13/2

4 1/3 converts to 13/3

Then, find a common denominator.

The LCM is 6. Now multiply the numerators.

13/2 * 3/3 = 39/6

13/3 * 2/2 = 26/6

Now, divide the two.

39/6 / 26/6 = 1.5.

Because the shorter pencil is the base length, the second part of the ratio is 1.

The ratio of the larger pencil to the shorter pencil is 1.5 : 1.
