Alright! To solve this one you first have to find out what 1cm is equal to in km, to do that you have to divide 18km by 3cm:
[18 ÷ 3] = 6.
Now we know that 1cm is 6km. To find how far apart they are on the map you simply divide 54km by 6km:
[54 ÷ 6] = 9.
They are 9cm apart on the map.
The first one is right because the mean is the average so it has to be in between. Usually. Hoped this helped!
Answer:
7
Step-by-step explanation:
<u>Concepts:</u>
- Division: a system of distributing a collection of things into equal parts
- Fractions: #s that represent a part of a whole
- Dividing Fractions: dividing a fraction by another fraction = multiplying the fraction by the inverse (reciprocal) of the other one
- Inverse Operations: operations that are opposite of each other (e.g. inverse of addition is subtraction)
<u>Solving:</u>
1. First, let's set up the equation:
7/8 ÷ 1/8
2. We can get the reciprocal of 1/8 by doing the opposite of division; multiplication. 1/8 becomes 1 · 8, and that's equal to 8.
3. Now, since we know dividing a fraction by another one is exactly the same as multiplying the fraction by the reciprocal of the other, let's multiply 7/8 by the inverse of 1/8, which is 8.
7/8 · 8 = 56/8 = 7
Therefore, 7/8 divided by 1/8 is equal to <u>7</u>.
