Question

Express as decimals: 7rupees 7paise (in rupees).

Answer 1

Hint: Here, first we have to convert all properties into one same unit that is to convert Rupees into paise. Then add all the values once we have the sum we can divide it with the appropriate number to get decimal value from it.

Complete step-by-step answer:
Let’s start by converting Rupees to paise.
Firstly, convert 7 Rs to paise:
As, \[1Rs = 100\,paise\]
We will multiply it with 7 to get a value of 7Rs.
  \[7Rs = 7*100\,paise\]
That is equal to,
\[ \Rightarrow 700\,paise\]
Now we have to take the sum of both of the quantities that are 700 paise and 7 paise respectively and make sure both are having the same units.
After adding both quantities we get,
\[ \Rightarrow 707\,paise\]
Now, let’s divide the sum with 100 to convert it into decimal.
\[ \Rightarrow \dfrac{{707}}{{100}}\,rupees\]
After dividing we get the decimal value that is,
\[ \Rightarrow 7.07\,rupees\]
Hence, 7 rupees 7 paise can be rewritten as 7.07 rupees.

Additional Information:
Multiply the appropriate number from the highest unit that is rupees in this case until the all values are having the same SI units. After converting we will add all the quantities and then we just have to divide by appropriate numbers according to the conversion used in question and get the exact decimal value.

Note: We can solve these types of questions with the conversion formulas used to convert one units to another. Make sure to make the units the same and add their values which have the same units. By calculating this, we can get the decimal value required in the question. Similarly, we can perform the questions of different units.
