To which set of numbers does the following number belong 6.3 repeating
1 answer:
6.3333... belongs to rational numbers.
Any number which can be represented in the form of p/q where is known as rational number.
Any repeating number is rational.
Proof:
Let x= 6.3333.......... -(i)
Multiply both sides by 10
10 x= 63.3333........... -(ii)
Subtracting equation i from equation ii
9x= 57
x= 57/9 which is in p/q form.

Answer:
1 : 3000
Step-by-step explanation:
Given that:
Scale measurement as following:
4 centimeters are equal to 120 meters.
To find:
The scale factor = ?
Solution:
First of all, let us learn about the definition of scale factor.
Scale factor means 1 unit on scale is equal to what length of actual measurement.
We are given that 4 cm on scale is equal to 120 meters of actual length.
We need to find nothing but how much 1 cm of scale is equal to actual length.
4 cm of scale = 120 meters or 12000 cm of actual length
Dividing by 4 on both sides, we get:
= 1 cm of scale =
= 3000 cm of actual length
Therefore, the scale factor is <em>1 : 3000</em>
