Describe the difference between the set of whole numbers and the set of natural numbers?
2 answers:
The set of counting numbers is called the set of natural numbers.
(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
When we include 0 in the set of natural numbers, the new set is called whole numbers.
(0, 1, 2, 3, 4, 5, 6, 7)
All natural numbers are included in the set of whole numbers. We can represent the relationship between these two sets of numbers using a diagram.

Step-by-step explanation:
Since the triangles are similar the ratios of corresponding sides are equal
=
, that is
=
( cross- multiply )
20(4x + 2) = 84x
80x + 40 = 84x ( subtract 80x from both sides )
40 = 4x ( divide both sides by 4 )
x = 10
