Acar 30.5m long, estimate the lenght of this car in feet

To answer this problem, all you need to have is to know the conversion from what to what. In this case, the conversion that you have to know is the conversion from meters to feet. The conversion from meters to feet is the 1 meter is equal to 3.28 feet. What would happen next is to take the given variable which is 30.5 meters and multiply it to 3.28 feet. For easier solving, it looks like this: 30.5 x 3.28

The answer to this would be 100.4 feet.

As for the unit used, it would look like this:

meter / feet = meter / feet
1 meter / 3.28 feet = 30.5 meters / x feet
(cross multiply)
30.5 meters x 3. 28 feet = 1 meter x xfeet
divide the whole equation with 1 meter so that x feet would be left since this is what we are looking for.
30.5 x 3.28 feet = x feet
100.4 feet = x feet

31 is prime. and it’s prime factorization is just 31.
