Woodchuck would chuck wood

It chucks 12 pounds per hour

So, it would chuck

                        12 X 20 = 240

pounds in twenty hours

It's a unitary method sum... in 1 hour he makes 12 pounds.. so in 20 hours he would make (12 x 20)pounds...i.e. 240 pounds

x = 12 hours 20x => 12 hours . 20 = 240 hours

1 hour = 12 pounds

20 hours = 12 pounds x 20 = 240 pounds

as a woodchuck would chuck twelve pounds of wood in an hour in 1hour - 12pounds of wood in 20hour - 12.20 = 240 pounds

1hour=12pounds 20hours=?

so we cross multiply which will give us 20x12=240

All you have to do is is multiply. You have to multiply 20 hours times 12 pounds, because that is how much he chuck within a hour. And this answer is 240 pounds

since , A woodchuck chuck 12 pounds of wood / hour then , it will chuck (x) wood / 20 hours cross multiply , we get : 12 * 20 = 240 p / h

20 hours 12 pounds 20 * 12 = 240

a woodchuck chucks in one hour twelve pounds of wood in twenty hour he would chuck about 12*20 = 240 pounds of wood

I basically did 20 hours multiply by 12 pounds per hour= 240 pounds in 20 hours.
