Explanation:

Step1: Solve 515×4 (e)

Break 515 into 500 + 10 + 5.

• \( 5 \times 4 = 20 \)
• \( 10 \times 4 = 40 \)
• \( 500 \times 4 = 2000 \)

Sum: \( 20 + 40 + 2000 = 2060 \)

Step2: Solve 938×2 (f)

Break 938 into 900 + 30 + 8.

• \( 8 \times 2 = 16 \)
• \( 30 \times 2 = 60 \)
• \( 900 \times 2 = 1800 \)

Sum: \( 16 + 60 + 1800 = 1876 \)

Step3: Solve 331×6 (h)

Break 331 into 300 + 30 + 1.

• \( 1 \times 6 = 6 \)
• \( 30 \times 6 = 180 \)
• \( 300 \times 6 = 1800 \)

Sum: \( 6 + 180 + 1800 = 1986 \)

Step4: Solve 167×3 (i)

Break 167 into 100 + 60 + 7.

• \( 7 \times 3 = 21 \)
• \( 60 \times 3 = 180 \)
• \( 100 \times 3 = 300 \)

Sum: \( 21 + 180 + 300 = 501 \)

Answer:

e. \( 515 \times 4 = 2060 \) (20 = 5×4, 40 = 10×4, 2000 = 500×4)
f. \( 938 \times 2 = 1876 \) (16 = 8×2, 60 = 30×2, 1800 = 900×2)
h. \( 331 \times 6 = 1986 \) (6 = 1×6, 180 = 30×6, 1800 = 300×6)
i. \( 167 \times 3 = 501 \) (21 = 7×3, 180 = 60×3, 300 = 100×3)
