A parasail is 1/20 of a meter above the water. Then, after 10 minutes, the parasail is 1/50 of a meter above the water. What is the change in height?

Answer 1

To find the change in height, we need to subtract the initial height from the final height.

The initial height is 1/20 of a meter above the water.
The final height is 1/50 of a meter above the water.

The change in height is: Final height - Initial height = (1/50) - (1/20).

To subtract these fractions, we need to find a common denominator. The least common multiple of 20 and 50 is 100.

(1/50) - (1/20) = (2/100) - (5/100) = (2 - 5)/100 = -3/100.

Therefore, the change in height is -3/100 of a meter above the water.
