Can someone help me pls

Step-by-step explanation:Understand p+q as the number located a distance |q| from p, in the positive or negative direction depending on whether q is positive or negative. Shows that a number and its opposite have a sum of 0 (are additive inverses). Interpret sums of rational numbers by describing real-world context.

Understanding subtraction of rational numbers as adding the additive inverse, p-q=p+(-q). Shows that the distance between two rational numbers on the number line is the absolute value of their difference, and apply thiss principle in real-world context.

Understand that integers can be divided, provided that the divisor is not zero, and every quotient of integers (with non-zero divisor) is a rational number. If p and q are integers, then -(p/q) = (-p)/q = p/(-q). Interpret quotients of rational numbers by describing real-world contexts.

i did it myself and i got 4.2 (b) hope its right
