2 : 3 = 6 : 9

10 : 12 = 5 : 6

8 : 5 = 16 : 10

3 : 1 = 6 : 2

2 : 10 = 1 : 5

5 : 4 = 15 : 12

6 : 4 = 3 : 2

5 : 3 = 10 : 6

Step-by-step explanation:

Equivalent ratios are those that can be simplified or reduced to the same value.

For example,

Reduce 10 : 6 = 5 : 3

Reduce 16 : 10 = 8 : 5

Reduce 15 : 12 = 5 : 4

Reduce 6 : 9 = 2 : 3

Reduce 6 : 12 = 1 : 2

Therefore,

2 : 3 = 6 : 9

10 : 12 = 5 : 6

8 : 5 = 16 : 10

3 : 1 = 6 : 2

2 : 10 = 1 : 5

5 : 4 = 15 : 12

6 : 4 = 3 : 2

5 : 3 = 10 : 6

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

but which class are u may know that first
