Kevin uses each of the digits 6,4,3 and 8, once and once only, to make four-digit numbers. (c)what is the largest number that he can make? (d)what is the smallest odd number that he can make?

(c) The largest number is 8643.

(d) The smallest odd number is 4683.

Step-by-step explanation:

Kevin uses each of the digits 6,4,3 and 8, once and once only, to make four-digit numbers.

(c)  Among those 4 digits, the largest digit is 8 and the order of digits from largest to smallest is:  8, 6, 4, 3

So, the largest number that he can make is 8643.

(d)  For getting odd number, the last digit should be odd. Here, 3 is the only odd digit. That means the last digit of the smallest odd number will be 3.

As the number should be smallest, so the order of the first three digits from smallest to largest will be:  4, 6, 8

Thus, the smallest odd number that he can make is 4683.
