Answer is D as in option A, 14/100 is shaded, which means 7/50 is shaded. In option B, 22/100 is shaded, which means 11/50 is shaded. In option C 29/100 is shaded. In option D, 20/100 is shaded, which means 1/5 is shaded.

Ans 2:

Class : Class 7
d) 20/100 because 20/100 is equivalent fraction of 1/5
