413/8 or 51.625 decimal
Step-by-step explanation:
Simplify the following:
(9 + 5/6) (5 + 1/4)
Put 5 + 1/4 over the common denominator 4. 5 + 1/4 = (4*5) / 4 + 1/4:
(9 + 5/6) (4*5) / 4 + 1/4
4*5 = 20:
(9 + 5/6) (20/4 + 1/4)
20/4 + 1/4 = (20 + 1) / 4:
(9 + 5/6) (20 + 1) / 4
20 + 1 = 21:
(9 + 5/6) * 21/4
Put 9 + 5/6 over the common denominator 6. 9 + 5/6 = (6*9) / 6 + 5/6:
21/4 (6*9) / 6 + 5/6
6*9 = 54:
((54/6 + 5/6) * 21) / 4
54/6 + 5/6 = (54 + 5) / 6:
21/4 (54 + 5) / 6
54 + 5 = 59:
59/6*21/4
59/6*21/4 = (59*21) / (6*4):
(59*21) / (6*4)
The gcd of 21 and 6 is 3, so (59*21) / (6*4) = (59 (3*7)) / ((3*2) 4) = 3/3 * (59*7) / (2*4) = (59*7) / (2*4):
(59*7) / (2*4)
2*4 = 8:
(59*7) / 8
59*7 = 413:
Answer: 413/8
