Question

Two hundred ten balloons are filled for a reception. This is 70 percent of the entire number of balloons purchased. Which equation can be used to find the total number of balloons purchased?

Answer 1

210 balloons divided by 70 (the percent) = 3 (1% = 3 balloons) 

3 times 100 = 300 Balloons

The total number of balloons purchased is 

300 balloons

Answer 2

Answer:

(0.70)x = 210

Step-by-step explanation:

Let the total number of the balloons purchased = x

210 balloons were filled for a reception.

this number is 70% of the total number of balloons purchased.

so 70% of x will be equal to  210

Therefore, equation will be

70% of x = 210

$\frac{70x}{100}=210$

(0.70)x = 210

Therefore, the equation can be used to find the total number of balloons is

(0.70)x = 210.
