Question

How do you write $1\dfrac{4}{5}$ (million) as an improper fraction?

Answer 1

Hint: The given fraction is known as a mixed fraction and we must convert it into an improper fraction. For that, we must multiply the denominator of the mixed fraction to the whole number, which is placed in front, and then add the numerator part. Then we write the calculated part in the numerator and write the denominator the same as given in the question.

Complete step-by-step solution:
The given fraction $1\dfrac{4}{5}$ is a mixed fraction.
We must convert it into an improper fraction.
Firstly, for that, we must multiply the denominator with the whole number of the mixed fraction and then add it to the numerator.
$\Rightarrow (5 \times 1) + 4$
On evaluating,
$\Rightarrow 9$
This must now be written in the numerator.
The denominator remains the same as that of the question.
Now writing it together we get,
$\Rightarrow \dfrac{9}{5}$
The units given in the question are millions.
Whenever we change a fraction from mixed to improper, the notation changes but the units remain the same.
So, just write as it is beside the improper fraction.

$\therefore 1\dfrac{4}{5}$ millions on converting into an improper fraction, we get, $\dfrac{9}{5}$ millions.

Note: While converting an improper fraction to a mixed fraction we must first divide the denominator with the numerator. Then we write the answer in the whole number part i.e., in front of the fraction. Now, we write the remainder in the numerator part and the denominator remains as it is. A mixed fraction is a whole number and a fraction part combined. The units will always remain the same.
