45000/36 = 1250 yards
45000/12 = 3750 feet
There are 12 inches in a foot and 5280 feet in a mile. But to convert 45000 inches into miles, I would just divide 45000 by 63360.
There are not enough inches there to be converted into miles because there are 63,360 inches in 1 mile
You could multiply by 1.3 and 63360.
5280 feet/ 1 mile and 12 inches/ 1 foot <3
To convert 1.3 miles into inches, you could multiply by the ratio 1 mile = 63,360 inches, or by the ratio 5,280 feet = 63,360 inches (since there are 5,280 feet in a mile).
I would use 1/36 to convert inches to yards and 1/1760 to convert yards to miles.
I suggest you convert the feet to inches (or vice versa, convert the inches to feet - but converting the feet to inches is easier), then it will be easy to compare the two measurements.
When two ratios form a proportion, the ratios are equal
1/60, twice. Just use 1/3600...
Two
To convert from meters to inches, divide by 0.0254. 2 meters is equal to 78.7402 inches.
Treat the ratios as fractions. One way you can compare them is to convert them to decimal (divide the numerator by the denominator, or the first number of the ratio by the second number), then compare. Another way is to find a common denominator, then compare the numerators.
