The Greatest Common Factor (GCF) for 3, 7, 8 is 1 3 = 1, 3 7 = 1, 7 8 = 1, 2, 4, 8
Points: (-3, -1) and (-7, -8) Slope: (-1--8)/(-3--7) = 7/4 or 1.75
1 and 7/8 + 2 and 3/8 = 4 and 1/4
3 1/4 - 1 7/8 3 2/8 - 1 7/8 2 10/8 - 1 7/8 = 1 3/8
3/7 × 56 = 3/7 × 56/1 = (3×56)/(7×1) = (3×7×8)/7 = 3×8 = 24.
3/(8-7)/8 = 3/1/8 = 3/8
11/7 / 22/3= 8/7 / 8/3= 8/7 x 3/8= 24/56= 3/7
3/7 × 1/8 = 3/56
4 and 7/8 - 3 and 6/8 = 1 and 1/8
1 1/8.There are usually different ways to solve the same problem. Here's one:2 7/8 - 1 3/4 = 2 + 7/8 - ( 1 + 3/4) = 2 + 7/8 - 1 - 3/4 = 2 - 1 + 7/8 - 3/4 = 1 + 1/8 = 1 1/8.Or, 2 7/8 = 23/8 and 1 3/4 = 7/4 = 14/8. So 23/8 - 14/8 = 9/8 = 1 1/8.
7/8 - 3/4 = 7/8 - 6/8 = 1/8
(7/8) - (3/8) / (9/1) = (7/8) - (3/8)*(1/9) = (7/8) - (1/24) = 21/24 - 1/24 = 20/24 = 5/6
