Question

using partial produc
135
× 3
□ = □ × □
□ = □ × □
□ = □ × □
□
614

Explanation:

Step1: Calculate first partial product

Multiply 3 and 5. $3\times5 = 15$

Step2: Calculate second partial product

Multiply 3 and 30. $3\times30 = 90$

Step3: Calculate third partial product

Multiply 3 and 100. $3\times100 = 300$

Step4: Sum the partial products

Add 15, 90, and 300. $15 + 90 + 300 = 405$ (Note: The given 614 at the bottom is incorrect; the correct product of 135×3 is 405.)

Answer:

First partial product: 15, Second partial product: 90, Third partial product: 300, Final product: 405
