3/5=12/20 1/4=5/20 3/5-1/4=7/20
2/7 - 4/7 = -2/7
(4/7)/(2/9) = (4/7)(9/2) = 36/14 = 18/7 = 2 and 4/7
2 over 9 divided by 4 over 7 is the same as 2 over 9 times 7 over 4 which is... 7 over 18 ....so the answer is 7 over 18
negative 2 over 7
4/7+4/14 = 4/7+2/7 = 6/7 4/14 = 2/7 after removing common factor 2
2/7 + 1/4 (2*4)/(7*4) + 7/(4*7) 8/28 + 7/28 (8 + 7)/28 15/28
4 over 7
It is 4 /49!
4 - 2/7 = 35/7
2 8/7 divided by 4/7 is the same as 8/7 times 7/4... The 7s then cancel out and you get 8/4 which is 2
1/4 x 16/7 = 4/7
