5 x 2 = 10 halves
2. x/10=1/5 cross multiply to denominators: 5x=10 x=10/5=2
2 with 10 remaining110 - 10 = 100 = 50 x 2
20 1 = 1/1 = 10/10, or 10 tenths. 2 x 1 = 2 x 10/10 = 20/10 = 20 tenths
first you forget the 2 is there. then you go : 1/10 x 1/10 x 1/10 x 1/10 x 1/10 x 1/10 = b now make b a 2. 2 x 10 -6 is 0.000002.

2' X 5' = 10 sq ft
10 = 10 x 1 40 = 10 x 2 x 2 100 = 10 x 2 x 5 least common multiple = 10 x 2 x 2 x 5 = 200
