This is already in simplest form. it can't be reduced furthermore.
As a mixed number is 5 1/4
As a decimal is 5.25
P = printer cost
C = computer cost
P + C = 900
C = 3P
P + 3P = 900
4P = 900
P = $225
C = 3(225)
C = $675

have a good day!!
Since 1/4 is equal to 0.25 than you would do 5,400 times 0.25 and get the answer of 13,500.0. So the race car weighs 13,500 pounds.
