27/50 as a decimal is 0.54, by finding the solution this is a method that I have used I first multiply 50, the denominator by 2 and 27 by 2 in the top which is 54/100 to convert the fraction 54/100 you notice that the the second place holder after the decimals is the hundredths you would have to place the 5 in the first placeholder then the 4 in the place holder.
27 *2= 54
50*2=100
54/100
Decimal form: 0.54

Answer:
Step-by-step explanation:
You have the right numbers, but the wrong accounts.
__
Let x represent the amount invested at 8% (the highest rate). Then the total interest is ...
.08x +.03(3000 -x) = .04(3000)
.05x = .01(3000) . . . . subtract .03(3000)
x = 3000/5 = 600
Matthew invested $600 at 8%, $2400 at 3%.
