Question

find the product of the largest 4digit number and the predecessor of the smallest 2 digit number.

Answer 1

Answer:

Required product = 89991

Step-by-step explanation:

Largest 4 digit number = 9999 ---(1)

Smallest 2 digit number = 10

Predecessor of 10 = 10-1 = 9 ---(2)

Product of the largest 4digit number and the predecessor of the smallest 2 digit number

= 9999 × 9

= (10000-1)×9

= 90000 - 9

= 89991

Therefore,

Required product = 89991
