Convert them to a common denominator, which in this case is 35 (5 x 7...the two denominators multiplied), so 3/5 becomes 21/35 and 4/7 becomes 20/35, therefore three fifths is greater than four sevenths.
it is 20 21s
2/7 = 10/35 3/5 = 21/35 10/35 + 21/35 = 31/35
(4/5)-2 = (5/4)2 = 25/16
No. 1/10 = .1 2/5 = .4

you have 18 over 7 and 8 over 5. These multiply to 144/35 which is 4 and 4 thirty-fifths.
4/7
That depends how many fifths there are.
The LCD of 2/7 and 4/5 is 35.
yes because if you think of it as slices of pizza you would get more slices with 2 sevenths of it.
7/10 divided by 2/5 is 1.75 or 1 3/4
well i am not sure but i think it does.
Two fifths is greater than two sevenths
Expressed as a decimal, 5 4/5 + (-3 2/7) = 2.5142857 recurring (that is, 2.5142857142857...)
it is basically 2/5 x 7/4 which is 14/20= 7/10
Yes, fifths arer bigger chunks than sevenths.
