Question

The problem really said convert 3 seconds into days. Then the next question was convert 2 inches into yards.

Answer 1

Here is some information for you:

There are 86,400 seconds in one day.

There are 3 feet in one yard = 36 inches in one yard.

3/86,400 = 1/28,800 days.

2/36 = 1/18 inches.

Is this what you wanted?

Answer 2

3 s (1 hr/3600 s)(1 day/24 hr) = 3.472222* 10^-5 days or .000034722222 days

2 in (1 yd/36 in) = (1/18)yd = .0555555 yd

Answer 3

Damon, I got the same answers except I replied using fractions.

Answer 4

sure.
I always multiply by one.
Anything the same top and bottom is one for me
like

(12 inches/1 foot)

is one to me because the same top and bottom

so
if I have 6 feet and want inches

I do

6 ft (12 inches/1 ft)
the foot units cancel, and I am left with 6*12 inches or 72 inches

If you have a whole string of conversions, for example in some chemistry problems, that multiplying repeatedly so the unwanted units cancel is a handy accounting tool.

Answer 5

I believe this is what we needed. Thanks so much!
