Answer 1

Answer:

300 balloons.

Step-by-step 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

$\frac{70}{100} \times x=210\\ \\ \frac{7x}{10} =210\\ \\ By\ cross\ multiplication\\ \\ 7x=210\times10\\ \\7x=2100\\\\ By\ dividing\ both\ sides\ by\ 7\\ \\ \frac{7x}{7} =\frac{2100}{7} \\ \\ x=300$

Therefore, total number balloons purchased was 300.
