Question

(Feeling very weak must complete in 3 days) Samantha had a board that was 6 ft. 8 in. long. She cut off a piece that was 2 ft. 10 in. long. How much board does she have left

Answer 1

You need to convert everything into one unit I would suggest inches. Do you know how to do that?

Answer 2

not really I don't think so

Answer 3

Well the conversion is 1 ft. = 12 in.
Using that can you work out how big the board was first of all?

Answer 4

10 ft 18 in?

Answer 5

Nope, first of all the question says it is 6 ft. 8 in. long and then you have to use the conversion on the 6 ft. to turn it into inches.
10 ft. 18 in. is longer than what you started with.

Answer 6

I see..

Answer 7

So what do you get for your starting length in inches? You need to convert the 6 ft to inches and then add the remaining 8 inches to the 6 ft in inches.

Answer 8

I think im adding this all up wrong I got 4ft 2 ;p hold on

Answer 9

You almost have it! You should have 6*12+8 = starting board
and 2*12+10 = the cut off part

Answer 10

80 is starting 34 is cut off part added together = 114

Answer 11

But it is asking how much board does she have left, so that is not addition.

Answer 12

Think about it if she throws away the piece she just cut off how much does she still have?

Answer 13

3 ft 10

Answer 14

That's what I got! :D

Answer 15

Answer 16
