No, it cannot.
The ratio 7 to 3 to 5 cannot be simplified.
2 * 2 * 3 * 5 * 7 = 420 2 * 2 * 2 * 3* 3 * 3 * 5 * 7 = 7560 1/18 is the simplified fraction
3/7 is simplified.
6/7 for the first one and 3/5 is allready simplified!
7/3 cannot be simplified since the two numbrs are prime.
6√5 + 2√5 - 7 = 8√5 - 7, which cannot be simplified.

5/21 * 7/20 = 5/3 * 1/20 = 1/3 * 1/4 = 1/12
It can't be simplified to a whole fraction - the next best you can have is 3-and-a-half over 5. 7 can't be cancelled down any further into a whole number.
No, it can't be simplified. There is no common factor of 3 and 7. They're both prime numbers...
2/5 + 3/10 = 4/10 + 3/10 = 7/10 and that cannot be simplified.
3/7 cannot be simplified.
