There is 94.11 meters in 100 yards how I got the answer is because I know that there is 0.9144 in 1 yard. I hope this helps and someone deleted my response so that is why I am responding again.!!!
Half = 1/2
Third = 1/3
To find 1/2 of 30 we need to multiply them.
1/2 x 30 = 30/2 = 15
To find 1/3 of 75 we need to multiply them.
1/3 x 75 = 75/3 = 25
25 is bigger than 15
Answer:
1/3 of 75 is bigger
