Given:
The width of a kitchen is 4.2 metres.
Kitchen cupboard widths are 60 cm.
To find:
The number of kitchen cupboard that will fit in 4.2 metres.
Solution:
Let x be the number of kitchen cupboard that will fit in 4.2 metres.
Width of 1 cupboard = 60 cm
Width of x cupboards = 60x cm
We know that, 1 m = 100 cm.
Width of a kitchen = 4.2 metres
= 4.2×100 cm
= 420 cm
Now, the width of the x cupboards is equal to width of the kitchen.
![60x=420](https://tex.z-dn.net/?f=60x%3D420)
![x=\dfrac{420}{60}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B420%7D%7B60%7D)
![x=7](https://tex.z-dn.net/?f=x%3D7)
Therefore, the number of kitchen cupboard that will fit in 4.2 metres is 7.
