Answer 1

d.) 9 5/21-(10-2/3-3 5/28)

=194/21-(10-2/3-3 5/2)

=194/21-(10-2/3-82/28)

=194/21-517/84

e.) 11-(4 5/6+3 3/10)

=11-(4+3)+(5/6+3/10)

=11-(7+(5/6+3/10)

=11-(7+17/15)

=11-(7+1 2/15)

=11-(7+1+2/15)

=11-(8+2/15)

=11-(8 2/15)

=11-122/15

=43/15

f.) 22 1/3-(10 7/12+9 11/20)

=67/3-(19+(7/12+11/20)

=67/3-(19+17/15)

=67/3-(19+1+2/15)

=67/3-(20+2/15)

=67/3-20 2/15

=67/3-302/15

=11/5

g.) 10-(5 7/8+3 5/12)

=10-(5+3)+(7/8+15/12)

=10-(8+7/8+5/12)

=10-(8+31/24)

=10-(8+1 7/24)

=10-(8+1+7/24)

=10-9 7/24

=10-223/24

=17/24

h.) 3 17/18-(6 1/6-3 11/21)

=65/18-(6 1/6-3 (11/21)

=65/18-(37/6-3 11/21)

=65-(37/6-74/21)

=65/18-37/14

=61/63

i.) 8 5/9-(5 7/24-2 13/36)

=77/9-(5 7/24-2 13/36)

=77/9-(127/24-2 13/36)

=77/9-(127/24-85/36)

=77/9-211/72

=45/8
