Final answer:
Jackie can paint 4 chairs.
Step-by-step explanation:
To find the number of chairs Jackie can paint, we need to divide the amount of paint she has by the amount required to paint one chair.
Jackie has 6/7 of a bottle of paint. The amount required to paint one chair is 5/25 of the amount Jackie has. To divide fractions, we multiply by the reciprocal of the second fraction.
6/7 ÷ 5/25 = 6/7 × 25/5 = 6/1 × 5/7 = 30/7.
So, Jackie can paint 30/7 or approximately 4.29 chairs.
Since Jackie cannot paint a fraction of a chair, the correct answer is D. 4 chairs.
