Question

What is $\dfrac{7}{{10}}$ of 650?

Answer 1

Hint: We are asked for the value of $\dfrac{7}{{10}}$ of 650. Here the term ‘of’ means multiplication. Hence the value is obtained from the product of $\dfrac{7}{{10}}$and 650.

Complete step-by-step answer:
We are given a number 650 and we are asked for the value of $\dfrac{7}{{10}}$ of it.
The term ‘of’ denotes multiplication .
So the required answer is obtained when we multiply the fraction $\dfrac{7}{{10}}$with 650.
So now lets multiply $\dfrac{7}{{10}}$ with 650
$
   \Rightarrow \dfrac{7}{{10}}*650 \\
   \Rightarrow 0.7*650 \\
   \Rightarrow 455 \\
$
Hence the value of $\dfrac{7}{{10}}$ of 650 is 455.

Note: Alternative method :
We can also find the value of $\dfrac{7}{{10}}$of 650 in another way
From this , lets first divide the number 650 into 10 parts
$ \Rightarrow \dfrac{{650}}{{10}} = 65$
Now we can see that we have divided 650 into 10 parts where the value of each part is 65.
That is , $\dfrac{1}{{10}}$of 650 is 65
Now $\dfrac{7}{{10}}$ can also be written as $7*\dfrac{1}{{10}}$
And we know the value of $\dfrac{1}{{10}}$ of 650.
Now , $\dfrac{7}{{10}}$ of 650 is given by $7*\dfrac{1}{{10}}$of 650
That is , 7 * 65 = 455

Additional information :
For finding a fraction of a whole number, we multiply the numerator of the fraction by the given number and then divide the product by the denominator of the fraction
Any part or part of a whole one is known as a fraction. A fraction is expressed by two numbers having a small horizontal line between them. The number above the small line is called the numerator or top number and the number below the small line is called denominator or bottom number..
