He will need 6 tenth size strips because if you put 3/5 vertically with another fraction beside of it that had the numerator blank and the bottom 10. You do this because Jeff uses fifth size strips so 5 represents the strips and you need tenth size strips so you find our numerator for the tenth size strips. You find out how many times 5 can go into 10 or 5 times what equals 10 and it's 2. So whatever you do to the bottom you do to the top. You times 5 by 2 at the bottom and get 10 for the tenth size strips and 3 times 2 at the top yoi get 6 and that is 6/10 is your answer
Answer:
7 in.
Step-by-step explanation:
2L + 2W = 16
Try L = 7
2(7) + 2W = 16
14 + 2W = 16
2W = 2
W = 1
If the length is 7 in., then the width is 1 in. That is perfectly acceptable, so L = 7 in. is a good value.
Try L = 8
2(8) + 2W = 16
16 + 2W = 16
2W = 0
W = 0
A length of 8 would make a width of 0. You can't have a rectangle with 0 width, so L = 8 does not work.
When L = 9 or L = 10, the width would be negative. The width of a rectangle cannot be a negative number, so these values doe not work.
Answer: 7 in.
So 1-9 so you can do 36 different combos just do 9x the amount of numbers so 4
