In reference to Q20, this involves reasoning and proofing under number series and operations. The learner requires the division operation to solve it.
For Q24, it involves problem-solving under measurement. The learner should have the
knowledge of multiplication and addition to be able to calculate the perimeter.
For the question on the number line, this is under number series and operations and involves presentation. The learner here requires an understanding of fractions, i.e., what each segment represents.
