BECE Mathematics 2025 Objective — Question 59

Question 59 of 120 from the Basic Education Certificate Examination (Junior WAEC) (BECE) Mathematics 2025 Objective paper, with the correct answer and a full explanation.

Use the sample to find the missing value in the last triangle (2/5 top-left, 4/5 top-right, 3/5 bottom).

• A. 2/5
• B. 3/5Correct
• C. 4/5
• D. 1 1/5

Explanation

In the samples, inside value = (top-left + top-right) − bottom (e.g. 1/2+1/2−1/2 = 1/2; 1/2+1/4−1/2 = 1/4; 2/3+1/3−1/4 = 3/4). So 2/5+4/5−3/5 = 3/5. (figure/print partly unclear).
