2/3 x 4/7 = 8/21Multiply across: 2 x 4 = 8, 3 x 7 = 21As 8/21 can't be simplified further the answer is 8/21
4/21 x 100 = 19.047619 recurring (that is, 19.047619047..) percent
21 x 4 = 84
21 x 4 = 84
x/4 + 5 = -1 (4)x/4 +(4)5 = -1 x+20 = -1 -20 -20 x= -21 x= -21
4 x 21 = 84 = (8 x 10) + (4 x 1)
x2 + 8x - 5 = 0 ∴ x2 + 8x + 16 = 21 ∴ (x + 4)2 = 21 ∴ x + 4 = ± √21 ∴ x = -4 ± √21
x-3-7x=21 -6x=21+3 6x=-24 x=-4
((1/3) x 4 )/21 = (4/3)/21 = 4/63

742 multiplied by 4 is 2,968.

You have x+4=25 so you minus the four from four and you minus the four from the 25 . and then you get 21 so it is x=21
4/21 x 100 = 19.047619 recurring (that is, 19.047619047619...) percent. Therefore, 4 is 19.047619... percent of 21.
