A spinner has 25 congruent sections. There are 12 orange, 4 red, 6 blue, and 3 purple sections on the spinner. Which decimal represents the probability that the first spin will stop on a blue section?

Given:

Total number of congruent sections = 25

Orange sections = 12

Red sections = 4

Blue sections = 6

Purple sections = 3

To find:

The probability that the first spin will stop on a blue section.

Solution:

The probability that the first spin will stop on a blue section is the fraction of number of blue sections and total number of sections.

Therefore, the required probability is 0.24.

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
