Hello,

An integer is a rational number (ex 5=5/1=10/2...)
The sum of 2 rationals is a rational.
Substract a rational is adding its opposite.
The difference of 2 rationals is always a rational (substraction is a intern law)

Answer:

When a habitat is destroyed, the carrying capacity for indigenous plants, animals, and other organisms is reduced so that populations decline, sometimes up to the level of extinction. Habitat loss is perhaps the greatest threat to organisms and biodiversity.

Question 2(Multiple Choice Worth 5 points) (04.01)The Boardman family walked two over five of a mile in two over seven of an hou

Zolol [24]

Answer:

The unit rate in miles per hour = <em>1.4 miles/hr</em>

Step-by-step explanation:

Given that:

Distance walked by Boardman family = Two over five of a mile = $\frac{2}{5}\ miles$

Time taken by Boardman family = Two over seven of an hour = $\frac{2}{7}\ hour$

To find:

The unit rate in the miles per hour = ?

Solution:

Formula for the rate or the speed can be given as:

$Speed = \dfrac{Distance}{Time}$

Putting the values:

$\Rightarrow \dfrac{\frac{2}5}{\frac{2}7}\\\Rightarrow \dfrac{7}{5}\\\Rightarrow \bold{1.4\ miles/hr}$

So, the unit rate in miles per hour = <em>1.4 miles/hr</em>
