Given : 13/17 and 0.82
To find : Which number is greater
Solution:
13/17 ? 0.82
13/17 ? 82/100
=> 13/17 ? 41/50
Cross multiplication
13 * 50 ? 41 * 17
650 ? 697
Hence
650 < 697
=> 13/17 < 41/50
=> 13/17 < 0.82
another method
13/17 ? 0.82
13/17 ? 82/100
=> 13/17 ? 41/50
=> 39/51 ? 41/50
on Left hand side numerator < right side &
also denominator on left side > Right side
hence
39/51 < 41/50
=> 13/17 < 0.82
Easier method depends upon user
