Question

3)

If 1/3
of a bucket of
sand covers 1/9 of a
playground, then how
much sand is needed for
the entire playground?​

Answer 1

For covering
`1` unit area of the entire playground, the amount of sand required is equal to volume of
`3` buckets of sand.

Explanation:

Given -

`(1)/(3)` volume of sand in bucket is able to cover
`(1)/(9)` area of the entire playground

Thus,

For covering
`(1)/(9)` unit area of the entire playground, the amount of sand required is equal to
`(1)/(3)` of the total volume of sand in bucket

For covering
`1` unit area of the entire playground, the amount of sand required is equal to

`((1)/(3) )/((1)/(9) ) \\\\(1)/(3) * (9)/(1) \\(9)/(3)\\= 3`

For covering
`1` unit area of the entire playground, the amount of sand required is equal to volume of
`3` buckets of sand.
