What are rational numbers?
1numbers which can be expressed as a ratio of two whole numbers where the
denominator is not equal to zero
2numbers which cannot be expressed as a ratio of two integers and the
denominator is always non-zero
3numbers which can be expressed as a ratio of two integers where the
denominator is not equal to zero
4numbers which can be plotted on a number line

The numbers which can be expressed as a ratio of two integers where the  denominator is not equal to zero

Step-by-step explanation:

Rational numbers are expressed in the form of where . 'q' is the denominator in the above fraction.

The fractional form which is terminating or non-terminating recurring are considered as rational numbers.

The numbers 'p' and 'q' are the integers.

Integers are defined as number which is a proper number and not a fraction or decimal. All negative whole numbers are considered as integers.

Some Examples of Rational numbers:   is a terminating fraction. is a non-terminating recurring fraction

Hence, the numbers which can be expressed as a ratio of two integers where the  denominator is not equal to zero

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
