18 x 35 = 630 630 / 30 = 21 So the answer is 21.
7/9 x 5/2 = 35/18 or 1 and 17/18

18 x 35 = 630
7+5x=(7/5)x multiply by 5 35 + 25x = 7x subtract 25x 35 = -18x divide by 18 x = (-35 / 18) now check 7+5(-35/18)=(7/5)(-35/18) 7-(175/18)=(7/5)(-35/18) (cast out 5 from the 5 and 35) (126/18)-(175/18)=(7/1)(-7/18) (-49/18)=(-49/18) and yes it does.◄
18 x 35 = 630 630 / 30 = 21 So the answer is 21.
