Question:

Which deal costs less per liter?

$32 for 4 liters

OR

$8.50 for 1 liter

How I solved this problem:

I know for the first deal that 4 liters is $32, but how much does it cost for 4 liters of the second deal. To work this out I times 8.50 by 4. The answer is $34 so the first deal costs less per litre.

]]>2 _ 6

X 3

_______

_ 3 _

How I solved it:

Firstly I worked out what three times six was. The product is 18 so I put down the eight and carry the one over to the next column. Next I figure out what three times something plus one equals that ends in 3. To do this I go through my three times tables until I reach three times four, which is twelve, and then add one which is thirteen. I put the 4 in the middle of the 2 and 6 and carry the 1 over to the next column. Then, 3 times 2 equals 6, plus I add the 1 that was carried over and the product is 7. I put the 7 down in the answer.

]]>1 _ 9

x 6

________

_ 5 _

**Answer:**

** **First I worked out that 6 times 9 is 54, so I put the 4 down in the unit column and carried the 5 to the next column.

Then I had to figure out 6 x ? plus the 5 carried over and the answer needed to end in 5. So I figured out that 6 x 5 is 30 and if I then add the carried 5 the answer is 35. The 5 is already in the answer so I just have to carry the 3 over to the next column.

Then I figured out that 6 x 1 plus the carried over 3 equals 9.

**Therefore the solution to the problem looks like this :**

^{3}1 ^{5}5 9

x 6

________

9 5 4

9 5 4

]]>Fill in the missing number.

36 ÷ ? = 4

*How I solved this problem:*

Since the product of the equation is 4, I went through my 4 times tables until I reached 36 which is 9 times 4. I then used division to make sure that the answer was correct.

The answer is 36 ÷ 9 = 4.
