Answer:
9:5
Step-by-step explanation:
- 112 - 40 = 72. 112 represents the total time, but you are comparing music to commercials, so you have to subtract the commercial time from the total time.
- Find the GCF of 72 and 40, which is 8.
- Divide 72 and 40. The simplified ratio is 9:5.
<span>1. Natural numbers are also known as "counting numbers", and are whole numbers starting at 1. A simple example set is {1, 2, 3, 4, 5}. The reciprocal of a number is 1 divided by that number. The reciprocal of 2 is 1/2; this is not a natural number.
2. The set of whole numbers includes natural numbers and zero. A simple example set is {0, 1, 2, 3, 4}. The opposite of 1 is -1; this is not a whole number.
3. The set of integers include whole numbers and their negative counterparts. A simple example set is {-2, -1, 0, 1, 2}. The reciprocal of 1 is 1, which is an integer.</span>
