Question

Scientists at zoo recently studied an anaconda that weighs 8,643.2 ounces.The average weight of the common rat is 11.8 ounces.About how many times heavier is the anaconda than the common rat?Explain why your answer is reasonable.

Answer 1

8,643.2 / 11.8 = 732.47 times bigger (thats rounded)

it is reasonable because 732.47 * 11.8 = 8643.14....it is not exact because I rounded the first answer....

Answer 2

Answer:

Step-by-step explanation:

Let the weight of anaconda will be n times the weight of rat.

We have been given that scientists at zoo recently studied an anaconda that weighs 8,643.2 ounces.The average weight of the common rat is 11.8 ounces.

We can represent our given information in an equation as:

$11.8\times n=8,643.2$

$\frac{11.8\times n}{11.8}=\frac{8,643.2}{11.8}$

$n=732.4745762$

$n\approx 732.47$

Therefore, the anaconda is approximately 732.47 times heavier than the common rat.

$11.8\times n=8,643.2$

$11.8\times 732.47=8,643.2$

$8643.146=8,643.2$

Since both sides of equation are equal, therefore, our answer is reasonable.
