Question

Anna wants to put a wire fence around each of her dinosaur fossils. She has 16 1/2 ft of fencing. How many dinosaur fossils will ana be able to put a fence around if each fossil requires exactly 2 2/3 ft of fencing? Note: you cannot have part of a fence

Answer 1

Answer:

The answer would be 5 fossils

Step-by-step explanation:

Technically, 16.5 x 2 2/3 = 5.5, but like the statement says: you cannot have part of a fence. So, the answer would be the closest whole, which is 5 fossils. I hope this helped!

Answer 2

Answer:

6

Step-by-step explanation:

You have 16 1/2 ft of fence, and each piece of fence is 2 2/3 ft. This is a division problem. You need to divide 16 1/2 ft by 2 2/3 ft.

$16 \frac{1}{2} \div 2 \frac{2}{3} =$

First, we change each mixed numeral into a fraction.

$= \dfrac{16 \times 2 + 1}{2} \div \dfrac{2 \times 3 + 2}{3}$

$= \dfrac{33}{2} \div \dfrac{8}{3}$

To divide fractions, you multiply the first fraction by the reciprocal of the second fraction.

$= \dfrac{33}{2} \times \dfrac{3}{8}$

$= \dfrac{33 \times 3}{2 \times 8}$

$= \dfrac{99}{16}$

$= 6 \frac{3}{16}$

The fencing material is enough for 6 and 3/16 fences, but since you cannot have a fraction of a fence, you can make 6 fences.
