300 balloons.

Explanation:

Given:

210 balloons are filled for a reception this is 70% of the entire number balloons purchased.

Question asked:

Which equation can be used to find the total number of balloons purchased ?

Solution:

Let total number of balloons purchased =
`x`

70% of the number of balloons purchased = 210

`(70)/(100) * x=210\\ \\ (7x)/(10) =210\\ \\ By\ cross\ multiplication\\ \\ 7x=210*10\\ \\7x=2100\\\\ By\ dividing\ both\ sides\ by\ 7\\ \\ (7x)/(7) =(2100)/(7) \\ \\ x=300`

Therefore, total number balloons purchased was 300.
