Question

Fill in the missing partial to help find 27 × 34

Answer 1

27 × 34 = 918

Solution:

27 × 34 using partial product.

27 = 27 + 7

34 = 30 + 4

Multiply 27 by 34

          = 27 × 34

          = (20 + 7) × (30 + 4)

Multiply each of the first term with each of the second term

          = 20 × (30 + 4) + 7 × (30 + 4)

          = (20 × 30) + (20 × 4) + (7 × 30) + (7 × 4)

          = 600 + 80 + 210 + 28

          = 918

27 × 34 = 918
