A dripping faucet loses about 2.5×10^−4 liters of water each minute. There are approximately 3×10^5 minutes in a month.

About how many liters of water are lost because of the dripping faucet in a month?



Drag and drop the values to the boxes to express the answer in scientific notation.

Answer 1

2.5 * 10^(-4) * 3 * 10^5 =

= 2.5 * 3 * 10^(-4) *10^5

= 7.5 * 10^(-4 + 5)

= 7.5 * 10^1

Answer 2

Let x liters of water is lost in a month.

2.5ₓ10⁻⁴ liters of water is lost in = 1 minute

∴ x liters of water will be lost in = 3×10⁵ minutes.
∴ x = 2.5×10⁻⁴ × 3×10⁵ = 75
∴ x = 7.5 × 10¹
