Three equivalent ratios to 5/2

Answers

To find equivalent ratios, we just need to perform the same action to each the top and bottom number.

5/2 = 5*2/2*2=10/4

5/2=5*4/2*4=20/8

5/2=5*10/2*10=50/20

Three equivalent ratios to 5/2 are
10/4 , 20/8 , and 50/20

The answer to this is 10/4,15/6 and 20/4

The GCF two numers is a composite number. Always, sometimes or never true?

Answers

Answer:

Sometimes

Step-by-step explanation:

A Composite number is the number which is not prime except 1. Hence, it has factors other than 1 and itself.

GCF is a greatest common factor i.e. the greatest factor that divides two numbers.

The GCF of two numbers can be composite number.

Example:

GCF of 8 and 24 = 8 which is a composite number.

GCF of 6 and 21 = 3 which is not a composite number.

Thus, GCF two numbers is sometimes a composite number.

The GCF of two numbers is sometimes a composite number.

Is a ice cube a polygon? why or why not?

Answers

No, because it is a cube shape and all shapes with four sides are polygons, and a ice cube is oblong /cuboid and it has 12 edges and 6 side.
hope I helped :)
also for more marks you could say that when ans ice cube melts it transfers into a different shape causing it to be a liquid, therefore if it was put in a polygon container, the water would be a ploygon

A Polygon is a two dimensional figure that can be drawn on a flat surface.A cube is a three dimensional figure that can be sculpted in three dimensions but can only have projections of it drawn on a flat surface.So a cube is not a polygon.
