Whats the sum of two rational numbers

The sum of two rational numbers is always a rational number.

Step-by-step explanation:

Rational Number is the number of the form , q≠0 and p and q are integers.

Further, when we add or subtract two rational number it is always a rational number. Example:

which is also a rational number.

Thus, the sum of two rational numbers is always a rational number.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
