5. A fraction is _ a rational number.
6. A natural number is _ a whole number.

5.A rational number is a fraction where the top and bottom number (numerator and denominator) are integers, a general fraction can have real or complex number and even algebraic expressions as numerator or denominator.

6.Natural numbers are the set of positive integers, that is, integers from 1 to ∞ excluding fractional n decimal part. They are whole numbers excluding zero. Natural Numbers are also called counting numbers. Zero is the only whole number which is not a natural number. It is represented by 0

Step-by-step explanation:

answer: 1 2 3 6

step-by-step explanation:

1x6=6 2x3=6

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
