Sagot :
13 5/9 - 8 1/6
= [ (13 * 9) + 5)/9 ] - [ (8*6)+1)/6 ]
= 122/9 - 49/6
= 122*6 - (49*9) / (9*6)
= ( 732 - 441 ) / 54
= 5.389
= [ (13 * 9) + 5)/9 ] - [ (8*6)+1)/6 ]
= 122/9 - 49/6
= 122*6 - (49*9) / (9*6)
= ( 732 - 441 ) / 54
= 5.389
An easy way to solve this problem is by finding the same denominators for both of the fractions. You can do this by multiplying 9 times 6 equals 54 and what you do to the bottom you must do to the top. So 5×6=30 and 1×9=9 13 30/54- 8 9/54 = 5 21/54 and then if you can simplify you do.
