Question

James has a square piece of paper. He wants to cut it into 20 strips of equal width. He says, 'This piece of paper is about 48 centimeters wide.' How can he find out the width of each strip without measuring? Is this width accurate?

Answer 1

Simply by dividing the with of the paper to the number of strips.
It will be=width of paper/no.of strips
=48/20
=2.4 cm..
Yes, this width is accurate..

Answer 2

Answer:  

The accurate width of each paper strip is 2.4 cm.

Solution:

When the total width and the number of equally divided parts is given then the width of divided part can be calculated by dividing the total width by the number of parts.  

Given, Width of the square paper = 48 cm

Number of strips to be cut = 20

$\text { The width of each strip }=\frac{\text { Width of the square piece }}{\text { total number of pieces to be cut }}=\frac{48}{20}=\frac{12}{5}$

$\text { Therefore, the width of each strip }=2.4 \mathrm{cm}$

The calculated width of each paper strip from the 48cm square paper piece is accurate.
