Answer 1

Explanation:

denominatiors are 25 and 64

25 = 5×5 = 5^2

= 2^0 × 5^2. ( 2^m × 5^n)

( anything^0 = 1 )

similarly,

64 = 2×2×2×2×2×2

= 2^6

= 2^6 × 5^0. ( 2^m × 5^n )

( 5^0 = 1 )

similarly,

4 = 2^2 × 5^0

3/4 = 3 × 5^2 / 4 × 5^2 = 3×25 / 4 ×25

= 75 / 100

3 / 4 = 0.75

7 /25 = 28 / 100 = 0.28

51 / 64 = 51 × 5^6 / 64 × 5^6

= 796825 / 1000000

=0.796825
