Answer:
77% and as a fraction it would be 77/100
Step-by-step explanation:

Answer:
120 4-digit numbers.
Step-by-step explanation:
For the numbers to be divisible by 5 they must end in 5.
So the total number of first 3 digits of the 4-digit number are given by the
number of permutations of 3 from the numbers 1,2,3,4,6 and 7 (6 digits)
= 6P3
= 6! / (6-3)!
= 6*5*4
= 120.
15 days because if it’s 1/5 a day then in 5 days it’ll be 5/5 times 3 which is 15 days
