8 1/2 ft and 18 1/3 ft how many square ft will be blue
Simplify the following:
(8+1/2) (18+1/3)
Put 18+1/3 over the common denominator 3. 18+1/3 = (3×18)/3+1/3:
(8+1/2) (3×18)/3+1/3
3×18 = 54:
(8+1/2) (54/3+1/3)
54/3+1/3 = (54+1)/3:
(8+1/2) (54+1)/3
54+1 = 55:
(8+1/2)×55/3
Put 8+1/2 over the common denominator 2. 8+1/2 = (2×8)/2+1/2:
((2×8)/2+1/2 55)/(3)
2×8 = 16:
((16/2+1/2)×55)/(3)
16/2+1/2 = (16+1)/2:
((16+1)/2×55)/(3)
16+1 = 17:
17/2×55/3
17/2×55/3 = (17×55)/(2×3):
(17×55)/(2×3)
2×3 = 6:
(17×55)/6
