You deposit some money into a bank account paying 8% simple interest per year. You received $500 in interest after 2 years. How much the deposit (principal) was?
Result
The principal was $3125.
Explanation
Find principal by using the formula I=P⋅i⋅t, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.
In this example I = $500, i = 8% and t = 2 years, so
IPPP=P⋅i⋅t=Ii⋅t=5000.08⋅2=3125

16-3/4=15 1/4
You can convert to fractions first, and then convert back to a mixed number like:
16/1-3/4  and when you add/subtract fractions you need a common denominator
64/4-3/4
61/4
15 1/4
Or you can convert your fraction to a decimal to get:
16-0.75
15.25
