Answer:
Here's how to subtract 3/4 from 7/8:
7
8
−
3
4
So we multiply 7 by 4, and get 28.
Then we multiply 3 by 8, and get 24.
Next we give both terms new denominators -- 8 × 4 = 32.
So now our fractions look like this:
28
32
−
24
32
Since our denominators match, we can subtract the numerators.
28 − 24 = 4
So the answer is:
0.284, is it right
