43% of 28= 43% * 28= 0.43 * 28= 12.04
They are: 30*20, 30*8, 2*20 and 2*8.

5630 is a single number and single numbers do not have partial products.

20 x 40 = 800 8 x 40 = 320 3 x 20 = 60 3 x 8 = 24
They are 600, 240, 80 and 32.
34 x 28 = 34 x (20 + 8) First partial product is: (30 + 4) x 8 = 240 + 32 Second partial product is: (30 + 4) x 20 = 600 + 80 Sum of partial products = total product = 600 + 240 + 80 + 32 = 952
43% of 28= 43% * 28= 0.43 * 28= 12.04
The partial products of 28 x 14 are 112 and 280. 28 = 8 + 20 ⇒ 28 x 14 = 8 x 14 + 20 x 14 = 112 + 280 14 = 4 + 10 ⇒ 28 x 14 = 28 x 4 + 28 x 10 = 112 + 280 The partial products are the same in the different splits as 28 = 2 x 14. If the numbers had been, say, 17 x 28 then: 28 = 8 + 20 ⇒ 28 x 17 = 8 x 17 + 20 x 17 = 136 + 340 17 = 7 + 10 ⇒ 28 x 17 = 28 x 7 + 28 x 10 = 196 + 280
They are: 30*20, 30*8, 2*20 and 2*8.

how to find the partial products of a number
4 x 20 = 80 4 x 7 = 28 80 + 28 = 108 4 x 27 = 108
60 x 40 = 2400 8 x 40 = 320 60 x 3 = 180 8 x 3 = 24 68 x 43 = 2924
the partial products for 12 and 3 30 and 6 :)
