Ratio 2 : 7 now we make the second side 1 as it's data is given so divide both sides by 7 2/7 : 1 now for second quantity 9.9 is given so multiply both sides with 9.9 9.9 * (2/7) : 1 * 9.9

Ummm
anonymous
  • anonymous
is it 3.25
nubeer
  • nubeer
nop.. can you put steps so i can tell where u made mistake.,

26
nubeer
  • nubeer
noo.. let me explain 5y-20=3y+6 first add 20 on both sides.
anonymous
  • anonymous
26
nubeer
  • nubeer
5y = 3y +26
anonymous
  • anonymous
ok
nubeer
  • nubeer
now subtract -3y on both sides.
anonymous
  • anonymous
2y
nubeer
