Answer:

23 is the smallest number

Step-by-step explanation:

Three consecutive numbers are numbers that come in a row. So if the first number is n then the next is n+1 and the following is n+2.

All together they add to 72.

So n + n+1 +n +2 = 72.

3n + 3 = 72

3n = 69

n = 23

Can 18 feet and 5 yards be expressed as a ratio in simplest form
Nuetrik [128]
1 yard is 3 feet.
18/3 = 6
Therefore, the actual ratio is 6 yards to 5 yards. Getting rid of like terms, we find that the simplest form ratio is 6:5
