Work Step by Step

In order to figure out how to write a decimal as a fraction, consider what place each digit of the number is. In the case of 8, it is in the tenth place, so it is the same as 8/10, which equals 800/1000. Meanwhile, 7 is in the hundredths place, so we know that this is equal to 7 divided by 100, or 7/100, which equals 70/1000. Finally, we know that 5 is in the thousandths decimal place, so it is the same as 5/1000. We add these together to get 875/1000, which simplifies to 7/8.
