126/7= 1 7 56/ 7=8 18 x 7 = 126. Answer: 18 times
-18
5/12:7/18= (5/12)/(7/18)= (5/12)*(18/7)= 15/14
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 minus 11 is 7.
