Question

Suppose one bottle of paint can cover $ 20 $ tiles. You have $ 348 $ tiles. How many bottles of paint do you need to buy to cover all $ 348 $ tiles?

Answer 1

Hint: Here first of all we will assume that one bottle contains one litre of paint. And will assume that there are “x” number of bottles used to paint the total $ 348 $ tiles. And here we will use the concept of cross multiplication and will simplify for the required value.

Complete step-by-step answer:
Let us assume that one bottle contains one litre of paint.
With every one litre, we can paint $ 20 $ tiles.
Also, suppose that “x” litres of paints are required to paint $ 348 $ tiles.
Frame the mathematical expression from the above word statements.
 $ \therefore x = \dfrac{{348 \times 1}}{{20}} $
Simplify the above equation –
 $ \Rightarrow x = 17.4 $ litres
Hence, $ 17.4 $ litres of paint were used to paint $ 348 $ tiles.
This is the required solution.
So, the correct answer is “ $ 17.4 $ litres”.

Note: Always read the word statements twice, as it is the base of the further solution so understand it perfectly and then convert it in the form of mathematical expressions. Be good in multiples and division. Since it is the most important fundamental to solve and simplify any mathematical expression. Remember multiples till twenty numbers. Always try to convert the given number in the prime numbers and then find the common factors in the numerator and the denominator and then remove them.
