b. 3/101, 4/101, 7/101, 18/101, 29/101
c. 54/1, 10/2, 9/2, 18/4, 17/8, 34/32 33/256

36/40, 47/101, 192

Step-by-step explanation:

(a)The numerator (top number of the fraction) is adding up by odd numbers in order.

From 1/40 to 4/40 you add 3, from 4/40 to 9/40 you add 5, from 9/40 to 16/40 you add 7, and from 16/40 to 25/40 you add 9.

The next number to add would logically be 11. So from 25/40 you would go to 36/40.

36/40 is your next fraction.

(b)

3+4=7,4+7=11,7+11=18,11+18=29,18+29=47

(c) 1*2=2,2*2=4,2*4=8,4*8=32,8*32=256,32*256=8,192
