80 x 70 = 5600 - 35 = 5565
80 - 70% = 80 x (1 - (70/100)) = 24
80 - 45 = 35
80 minus 35 is 45.

You could add all 50 test scores or use frequency. Add 35 times 80 percent to 15 times 70 percent and then divide by the 50 students.
you mean just the basic fraction? there are a ton. 70/80, 35/40, 49/56, 70000000000/80000000000 just do the top one times something and do the bottom one times the same number ex. 7/8 = 70/80 7 x 10 = 70, 8 x 10 = 80 its easy

5600 !

Yes because if u have 72 minus 80 is 8 and 7 minus 8 is 1.U have more left over than 7 out of two. --- Yes, 72/80 is greater than 7/8. However, I feel that the original answer (above) gives and incorrect explanation, because: 1. 72 minus 80 equals negative 8, not 8. 2. 7 minus 8 equals negative 1, not 1. 3. The method used is completely wrong. The correct explanation is: 7/8 = (7x10) / (8x10) = 70/80 Now that the denominators for both fractions are 80, you can compare the numerators. 72 is obviously greater than 70, so 72/80 is, of course, greater than 70/80. Since 72/80 > 70/80, 72/80 > 7/8
