  1. Answer:

    10. An hour (1 hour) = 60 minutes

    ∴ Requird fraction = 60/45

    = 4/3

    11. The natural numbers from 87to97 are 87,88,89,90,91,92,93,94,95,96and97.

    Total number of natural number =11

    Out of these, the prime numbers are 87and97

    Total number of these prime numbers = 2

    ∴ Required fraction = 11/2
