Answer:

99+30=69

69/3=23

Is 56/7 a rational number or
Sati [7]

Answer:

Yes

Step-by-step explanation:

The definition of a rational number is a number that can be represented as a fraction. Since 56/7 is a fraction it must be a rational number. An irrational number is a number that cannot be represented as a fraction because it never ends and repeats without a pattern forever. An example of this is pi because pi can never exactly be represented as a fraction.
