well 7-6 is one then you'll find common demonstrators with the fractions then simplify them then subtract them to get 1 1/4
I think the answer is B false
The one that says the combined area of the 4 triangles......
7 = 7
20 = 2 x 2 x 5
Least common multiple is 2 x 2 x 5 x 7 = 140
Other multiples are multiples of 140 = 280, 420, 560, 700
