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
2/7 + 1/4 (2*4)/(7*4) + 7/(4*7) 8/28 + 7/28 (8 + 7)/28 15/28
It is 4 /49!
4 over 7.
4/7 x 2/4 is 2/7
It is 5 3/7.
49/16 = (7^2)/(4^2) = (7/4)^2 = ((4/7)^-1)^2 = (4/7)^-2 Thus as (4/7)^2 = 49/16 and 49/16 = (4/7)^-2 (4/7)^x = (4/7)^-2 Therefore x = -2.
The sum of 5/7 and 2/4 is 1 3/14
4/9 ÷ 2/7 = 14/9 or 15/9
2/3 - 4/7 = 14/21 - 12/21 = 2/21
