Answer:
13/20 = 0.65 mile
Step-by-step explanation:
Finding the difference of two fractions is usually done by first expressing each of them using a common denominator. Here, both 4 and 10 are factors of 20, so 20 is a suitable common denominator.
9/10 - 1/4 = 18/20 - 5/20 = (18 -5)/20 = 13/20
This can be expressed as a decimal:
13/20 = (13·5)/(20·5) = 65/100 = 0.65
9/10 of a mile is 13/20 of a mile larger than 1/4 of a mile. In decimal, that is 0.65 miles larger.
