Let's assume the middle number is x
then the smallest number is x-2
the greatest number is x+2
so the sum of the three number would be (x-2)+x+(x+2) and it equals 45
now we have an equation (x-2)+x+(x+2)=45
then we solve it 3x=45
x=15, which means the middle number equals 15
so the greatest number would be x+2=15+2=17
17 is the greatest number

<h3>What is Unitary Method?</h3>

Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Sue spent 1 hour 19 minutes less than Jared

Lucas spent 45 minutes less than Pete.

Pete spent 3 hours reading.

Since, pete spent 3 hours. So, Jared spent

= 3 hours or (180 minutes) - 45 minutes

= 2 hours 15 minutes.

Now, Seu spent = 2 hrs 15 minutes - 1 hour 19 minutes  

                           = 56 minutes
