(30 - 7 5/8) - (9 30/48 + 8 36/48) =
4 2/7 * 3 5/10 - (8 5/6 - 4 4/6) * 6/5 =
6 3/4 * 1 3/7 * 14/45 * 33 1/3 : 2 =
[1*(1 1/4 * 18 2/5)] + 4 - [(30 - 7 5/8) - (9 32/48 + 8 34/48)] =

Answer 1

(30 - 7 5/8) - (9 30/48 + 8 36/48) = (30-61/8-(9 30/48+8 36/48)=179/8-(77/8+35/4)=179/8-147/8=4

4 2/7 * 3 5/10 - (8 5/6 - 4 4/6) * 6/5 =30/7*7/2-(8 5/6-4 4/6)*6/5=15-(53/6-14/3)*6/5=
=15-25/6*6/5=15-5=10

6 3/4 * 1 3/7 * 14/45 * 33 1/3 : 2 = 27/4*10/7*14/45*33 1/3:2=135/14*14/45*33 1/3:2=3*100/3:2=100:2=50

[1*(1 1/4 * 18 2/5)] + 4 - [(30 - 7 5/8) - (9 32/48 + 8 34/48)] = 
=5/4*92/5+4-(30-7 5/8-(9 32/48+8 34/48))=23+4-(30-7 5/8-(9 32/48+8 34/48))=
=27-(30-61/8-(9 32/48+8 34/48))=27-(179/8-(29/3+209/24))=27-(179/8-147/8)=
=27-4=23

Answer 2

(30 - 7 5/8) - (9 30/48 + 8 36/48) = (30-61/8-(9 30/48+8 36/48)=179/8-(77/8+35/4)=179/8-147/8=4

4 2/7 * 3 5/10 - (8 5/6 - 4 4/6) * 6/5 =30/7*7/2-(8 5/6-4 4/6)*6/5=15-(53/6-14/3)*6/5=
=15-25/6*6/5=15-5=10

6 3/4 * 1 3/7 * 14/45 * 33 1/3 : 2 = 27/4*10/7*14/45*33 1/3:2=135/14*14/45*33 1/3:2=3*100/3:2=100:2=50

[1*(1 1/4 * 18 2/5)] + 4 - [(30 - 7 5/8) - (9 32/48 + 8 34/48)] = 
=5/4*92/5+4-(30-7 5/8-(9 32/48+8 34/48))=23+4-(30-7 5/8-(9 32/48+8 34/48))=
=27-(30-61/8-(9 32/48+8 34/48))=27-(179/8-(29/3+209/24))=27-(179/8-147/8)=
=27-4=23
