x equals 4 over 35
4/7 + 3/5 = 41/35 or 16/35
7 = 28/4
n = 35
That equals 35.
It is: 2/5 plus 4/7 = 34/35
3/10 x 4/7 is 6/35
x=negative 1 over 4
31 plus four is 35.
100-35
take this for example 4/5 divided by 7/8.you have to keep the first fraction the same 4/5 and reverse 7/8 into 8/7 take the numerator and switch it with the denominator. then you multiply 4 times 8 equals 32 and 5 times 7 equals 35 so the answer is 32/35! BY : AVERY LEVIN
