Partial products are the products obtained during the intermediate stages in order to complete a multiplication process.
Consider 68 [tex]\times[/tex] 43, we have to determine the partial products in this.
Now, [tex]68 \times 43[/tex]
Expanding this, we get
[tex](60+8) \times (40+3)[/tex]
= [tex](60\times 40) +(60 \times 3) + (8 \times 40) + (8 \times 3)[/tex]
= 2400 + 180 + 320 + 24
= 2924
Hence, [tex]8 \times 40=320[/tex] and [tex]8 \times 3 = 24[/tex] are the required partial products in the product of 68 and 43.
So, Option 3 and 4 are the correct answers.
