Question

A plant nursery in Westford keeps records of how many of its plants are annuals, biennials, and perennials. Biennials 2 9 Perennials 4 9 Annuals 1 3 Distribution of plant types If the nursery has a total of 81 plants, how many more perennials than biennials does it have?

Answer 1

To calculate how many more perennials than biennials there are at the nursery, multiply the total number of plants (81) by the respective ratios for biennials (2/9) and perennials (4/9). The nursery has 18 more perennials than biennials.

Step-by-step explanation:

To determine how many more perennials than biennials the nursery has, we need to calculate the number of each type based on the provided ratios and total number of plants. The ratio provided states that there are 2/9 biennials, 4/9 perennials, and 1/3 annuals. The total number of plants is 81.

First, calculate the number of biennials. The ratio of biennials is 2/9, so we multiply 2/9 by the total number of plants:
Number of biennials = (2/9) × 81 = 18 plants.

Next, calculate the number of perennials:

Number of perennials = (4/9) × 81 = 36 plants.

Finally, to find out how many more perennials than biennials there are:

More perennials than biennials = Number of perennials - Number of biennials = 36 - 18 = 18 plants more.
