Answer 1

$\huge{\pink{\underline{\underline{Answer:-}}}}$

Given:

50 km long path

Traveller completed 8% of path

To find:

Kilometer traveller covered = ?

Solution:

To find km traveller covered we have to find 8% of 50km

$\\ \\ \dfrac{8}{100} \times 50 \\ \\ = \dfrac{8}{10} \times 5 \\ \\ = \dfrac{8}{2} \\ \\ = 4 \: km$

Required answer:

Therefore, traveller covered 4km out of 50km long path

Basic points:

# To find number of a percentage

$\\ \dfrac{percentage}{100} \times total$

Example: 5% of 50

$\\ \dfrac{5}{100} \times 50 \\ \\ = 2.5 \\ \\ 2.5 \: \: is \: \: 5\% \: of \: \: 50$

# To find percentage of number

$\\ \: \dfrac{number}{total \: number} \times 100$

Example: 2.5 of 50

$\\ \dfrac{2.5}{50} \times 100 \\ \\ = \dfrac{25}{5} \\ \\ = 5\% \: \\ \\ 2.5 \: \: is \: \: 5\% \: \: of \: 50$
