Well, isn't that a happy little math question! To simplify 71 over 42, we can divide the top and bottom by their greatest common factor, which is 1. So, 71 over 42 is already in its simplest form, just like a beautiful painting that doesn't need any more brushstrokes.
42 = 21 x 31 x 71 126 = 21 x 32 x 71 210 = 21 x 31 x 51 x 71 Take the lowest power of the common primes: hcf of 42, 126 & 210 is 21 x 31 x 71 = 42.
35/42 + 36/42 = 71/42 = 1 and 29/42

Converting percentage to a decimal: 42% = 42 / 100 = 0.42 42% of 71 = 42% * 71 = 0.42 * 71 = 29.82

42 = 21 x 31 x 71 126 = 21 x 32 x 71 210 = 21 x 31 x 51 x 71 Take the lowest power of the common primes: hcf of 42, 126 & 210 is 21 x 31 x 71 = 42.
It is: 21*31*71 = 42
35/42 + 36/42 = 71/42 = 1 and 29/42
I would estimate 29.
The GCF is 1.
