Give four examples for rational numbers equivalent to:
(i) -5/7
(ii) 40/80

Step-by-step explanation:

(i) -5/7

Here, we can write in the form of p and q. where, p = -5 and q = 7

(ii) 40/80 = 1/2

Here, we can write in the form of p and q. where, p = 1 and q = 2

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
