Question

S.I = P X r X t where r represents the rate. Rates must be converted into ____ before multiplying. ​

Answer 1

Answer:

already answered by me. the unit of time (eg. annum) and the unit given in rate (10 percent per annum) should be same

Answer 2

Answer:

Rate of interest is taken in percentage, $r\%$ or $\frac{r}{100}$.

Step-by-step explanation:

Simple interest is calculated using the formula:

                             $S.I = P \times r \times t$

where P is the Principal amount

           r is the rate of Interest in % per annum

   and t is the time calculated for number of years.

The rate of interest is taken in percentage, $r\%$ per annum.

Before multiplying it is taken as $\frac{r}{100}$.
