Q. What happens to the value of the expression q20 \frac{q}{20} as q q decreases?\newlineChoose 11 answer:\newline(A) It increases.\newline(B) It decreases.\newline(C) It stays the same.
  1. Analysis of the expression: Let's analyze the expression (q)/(20)(q)/(20). This is a direct proportionality between qq and the value of the expression. As qq changes, the value of the expression will change in the same direction because the denominator, 2020, is a constant positive number.
  2. Effect of decreasing qq: Now, let's consider what happens when qq decreases. Since qq is in the numerator, if we decrease qq, the overall value of the fraction q20\frac{q}{20} will also decrease. This is because we are dividing a smaller number by the same positive constant.
  3. Confirmation through example: To confirm our reasoning, we can think of a simple example. If qq decreases from 2020 to 1010, the value of the expression changes from (20)/(20)=1(20)/(20) = 1 to (10)/(20)=0.5(10)/(20) = 0.5. Clearly, the value of the expression has decreased.
