30 x 5 = 150
2 x 5 = 10
32 x 5 = 150 + 10 = 160
4 x 40 = 160 4 x 8 = 32 160 + 32 = 192 4 x 48 = 192
To find the partial products for 15 x 32, you can break down the numbers: 15 can be expressed as 10 + 5, and 32 as 30 + 2. You then calculate: 10 x 30 = 300 10 x 2 = 20 5 x 30 = 150 5 x 2 = 10 Adding these partial products together: 300 + 20 + 150 + 10 = 480. Thus, the answer for 15 x 32 is 480.
45 = 3 x 3 x 5 or 32 x 5
2475 = 3 x 3 x 5 x 5 x 11 OR 32 x 52 x11
The first partial product of 26 x 107 is calculated by multiplying 26 by the tens digit of 107, which is 100. Thus, the first partial product is 26 x 100 = 2600.
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
(40 x 5) + (2 x 5)
4 x 40 = 160 4 x 8 = 32 160 + 32 = 192 4 x 48 = 192
40 x 5 = 200 2 x 5 = 10 42 x 5 = 210
24 x 32 x 5
45 = 3 x 3 x 5 or 32 x 5
1,260 = 22 x 32 x 5 x 7
90 = 2 x 3 x 3 x 5 OR 2 x 32 x 5
2475 = 3 x 3 x 5 x 5 x 11 OR 32 x 52 x11
360 = 23 x 32 x 5
Expressed as a product of its prime factors, 2520 = 23 x 32 x 5 x 7
45 = 32 x 5
