Whenever you add or subtract fractions you have to have the denominators the same so that the numerator is of the same value system.
For example you have 8/16 - 8/32
If you were you to subtract it without changing denominators to the same it would be equal to zero but when you change them to the same denominator
16/32 - 8/32 then the answer would be 8/32.

Answer:
annual interest rate is 7.25 %
Step-by-step explanation:
Given data
rate = 7% compounded daily
to find out
APR
solution
we have given rate 7 % compounded daily
so we convert it annually by dividing 365
we consider in 1 year 365 days
rate = 7% = 0.07/365
so annual interest rate is (1+r)^n -1
put the value of rate r here
annual interest rate = (1+r)^n -1
annual interest rate = (1+0.07/365)^(365) -1
annual interest rate = (1.000191781)^(365) -1
annual interest rate = 1.072500 - 1
annual interest rate = 0.072500
annual interest rate is 7.25 %
Answer: 20%
Step-by-step explanation: Since the number changes from 15 to 18, it's getting bigger which means it increases. To find the percent increase, we use the formula shown.
The amount of change is the difference between the two numbers. In this case, we would subtract 18 - 15 which equals 3. Then, we put 3 over our original number which is 15.
3 ÷ 15 = 0.2
Now, we need the percent increase which means we need to write 0.2 as a percent by moving the decimal point two places to the right to get 20%.
Therefore, the percent increase is 20%
