280x <= 348.76, or -280x + 348.76 >= 0,
so a = -280, b = 348.76 and c = 0 is one solution
Multiplying fractions: multiply numerators and multiply denominators
1. 3/4 X -6/7 = -18/28 = -9/14
2. -2/7 X -3/7 = 6/49
3. 4 because 72/9 is 8. -72/-9 is 8. Two negatives makes a positive when multiplying and dividing.
