there are 76 birdhouses, if 4 birdhouses are occupied, how much percent of the birdhouses are occupied?

Llana [10]

To find the percent of the birdhouses occupied, divide the number of occupied birdhouses by how many birdhouses there are in total:

$4 \div 76 = 0.0526$

Convert this decimal into a percentage by multiplying by 100:

$0.0526 \times 100 = 5.26$

5.26% of the birdhouses are occupied.
