To find out how much rainwater Karen uses to clean her bicycle, we need to calculate half of 6/7 quart. To do this, we'll divide 6/7 quart by 2.

First, let's convert 6/7 quart into a decimal:
6/7 ≈ 0.857 (rounded to three decimal places)

Now, let's divide 0.857 by 2 to find half of it:
0.857 ÷ 2 ≈ 0.429 (rounded to three decimal places)

Therefore, Karen uses approximately 0.429 quart of rainwater to clean her bicycle.

Next, we need to determine how much rainwater remains after cleaning the bicycle. We'll subtract 0.429 quart from the original 6/7 quart.

To do this, let's convert 6/7 quart into a decimal:
6/7 ≈ 0.857 (rounded to three decimal places)

Now, subtract 0.429 quart from 0.857 quart:
0.857 - 0.429 ≈ 0.428 (rounded to three decimal places)

So, after cleaning her bicycle, Karen has approximately 0.428 quart of rainwater left.

Finally, Karen wants to equally water 3 plants with the remaining rainwater. To find out how much water each plant will receive, we'll divide 0.428 quart by 3.

0.428 ÷ 3 ≈ 0.1427 (rounded to four decimal places)

Therefore, each plant will receive approximately 0.1427 quart of rainwater.
