38 over 50 simplified = 19/25
34/38 = 17/19
9/40 is already simplified.
51 and 40 are coprime so the ratio 51/40 cannot be simplified.
No
7/40 cannot be simplified since 7 is a prime number.
38/77 cannot be simplified further.
40/52 = 10/13
Expressed as a decimal fraction, 38/40 = 0.95
no 31 over 40 cannot be simplified. it can't be simplified because when you divide 40 by 31 you get 1.290322581. as you can see: not a whole number. to know if any fraction can be simplified when you divide them (denomiantor or bottom number first) the outcome must be a whole number.
