Question

Sara read 81 pages in her book. Colin read 64 pages in his book. How many more pages did Sara read than Colin?

Answer 1

Hint: Here in this question, we have to find the number of pages Sara read more than Colin, for this we need to calculate the difference between the number of pages read by Sara and Colin means subtract number of pages Sara read by number of pages read by colin by using the subtraction, we get the required solution.

Complete step by step solution:
 In mathematics we have four different kinds of arithmetic operations namely
Addition, which adds the numbers and the sign for the addition is +
Subtraction, which subtracts the numbers and the sign for the subtraction is –
Multiplication, which multiplies the numbers and the sign for the multiplication is \[ \times \]
Division, which divides the numbers and the sign for the division is \[ \div \]
By consider the given data in question:
Sara read 81 pages in her book.
Colin read 64 pages in his book.
To know how many more pages Sara read than Colin.
We need the difference of 81 and 64 or Subtract 64 from 81. To do this, we should use basic subtraction method, then
i.e., Number pages read by Sara \[ - \] Number pages read by Colin.
\[ \Rightarrow \]81\[ - \]64
On subtracting, we get
\[ \Rightarrow \]17
Therefore, Sara read 17 more pages in her book than Colin.
So, the correct answer is 17”.

Note: While using the arithmetic operations we must know about the numbers and the tables of multiplication. This is a word problem, where the word problem is converted into the numeral form. The arithmetic operations are used whenever it is needed and then we have to simplify.
