(5/11) - (2/7) = (35/77) - (22/77) = 13/77
5/9-1/3 is the same as 5/9-3/9. This would then subtract out to be 2/9. (2 over 9)
(7/8) - (3/5) = (35/40) - (24/40) = 11/40 = 0.275
5 days 4 hours - 2 days 11 hours = 2 days 17 hours
173/5 - 1/2 = 176/10 - 5/10 = 171/10
7/8 minus 2/3 is 5/24
11
11/40
5/9-1/3 is the same as 5/9-3/9. This would then subtract out to be 2/9. (2 over 9)
1 minus 5/16 = 11/16.
(7/8) - (3/5) = (35/40) - (24/40) = 11/40 = 0.275
5 days 4 hours - 2 days 11 hours = 2 days 17 hours
3 over 4= 0.75 1 over 5= 0.20 Subtract and you get: 0.55, or 11 over 20.
173/5 - 1/2 = 176/10 - 5/10 = 171/10
7/8 minus 2/3 is 5/24
2/5 x 10/11 = 20/55 = 4/11
6 + 2K = 11 subtract 6 from each side - 6 + 6 + 2K = 11 - 6 2K = 5 divide the integers both sides by 2 K = 5/2 check 6 + 2(5/2) = 11 6 + 10/2 = 11 6 + 5 = 11 11 = 11 checks
To add/subtract fractions you need to bring both to a common denominator, then add/subtract the numerators(top) . e.g. 3 2/3 - 2 1/5 Convert to improper fractions. 11/3 - 11/5 Brinf to a common denomiator [11(5) - 11(3)] / (3 x 5) [55 - 33] / 15 [22] / 15 = 1 7/15 For addition , it is the same process , but add the numerators ( 55+ 33 = 88]
