19 divided by 5728 is going to be a VERY small number, are you sure you phrased that right?
5.95 + 2.95 = 8.9
8.9 + 29.95 = 38.85
62.35 - 38.85 = 23.5
So Daniel spent $23.50 on long distance calling
You can't do 4 1/4 minus 3/4. You have to turn the 4 1/4 into a improper fraction and then get the same denominator and then you can subtract. When it is a improper fraction, you can also cross cancel. Good Luck!
