ITPEC IP April 2020 Question 2
ITPEC IP April 2020 — Question 2 of 100
The binary product is 110111. Binary 1011 is decimal 11 and binary 101 is decimal 5, so the product is 55. Decomposing 55 gives 32 + 16 + 4 + 2 + 1, which sets the bits 110111.
Answer (d)
Why not others:
- 1111 is 15
- 10000 is 16
- 101111 is 47
- none equals the required product 55
Key rule: Binary multiplication can be performed with shifted partial products or by converting the operands and result through powers of two.
