0.875=7/8

Explanation:

You can start by changing it straight forward to 875/1000. Now you have to see if this fraction can be reduced.

Both numerator and denominator can be divided by 25 because the digits of tens and units form numbers divisible by 25 (75 and 0 respectively). If you reduce the fraction by 25 you get: 35/40. This fraction can be further reduced by 5, so you get 7/8. Since 7 is a prime number and 8 is not divisible by 7 you cannot reduce the fraction further, so the answer is:

0.875=7/8
