Answer 1

1/2 * 2/3 * 3/5=

= 1/1 * 1/1 * 1/5=

= 1/5




3 i 1/4 * 4/5 * 15/26=

= 13/4 * 4/5 * 15/26=

= 1/1 * 1/1 * 3/2=

= 3/2=

= 1 i 1/2



1/8 * 1 i 1/5  * 5 i 1/3 * 1/2=

= 1/8 * 6/5 * 16/3 * 1/2=

= 1/4 * 3/5 * 16/3 * 1/2=

= 1/1 * 1/5 * 4/1 * 1/2=

= 4/10=

= 2/5




3 i 3/5 * 2/3 * 3 i 3/4 * 1 i 1/9=

= 18/5 * 2/3 * 15/4 * 10/9=

= 2/5 * 2/1 * 5/2 * 5/1=

= 1/1 * 2/1 * 1/1 * 5/1=

= 10/1 =

= 10




3 i 2/3 * 1 i 3/5 * 2/11 * 6 i 1/4 * 1/10 * 4 i 2/7=

= 11/3 * 8/5 * 2/11 * 25/4 * 1/10 * 30/7=

= 1/3 * 8/5 * 2/1 * 25/4 * 1/1 * 3/7=

= 1/1 * 2/1 * 2/1 * 5/1 * 1/7=

= 20/7=

= 2 i 6/7
