Hot dog buns come in boxes of 8. On Friday's game, the chef uses 2 1/6 boxes of hotdog buns. On Saturdays game, the chief uses 1
Phantasy [73]

Answer:

3 and 5/6

We know this because it says the chef uses 2 1/6 boxes on one day and 1 4/6 on the other.

2 + 1 = 3

1/6 + 4/6 = 5/6 (cannot be simplified)

Put them together = 3 and 5/6

Kerri said that the product of 3.93 and 0.07 would be about 4 and would have two decimal places. Is she correct?
oee [108]

Answer:

No.

Step-by-step explanation:

This type of problem is actually a trick problem. The question indicates that the PRODUCT of 3.93 and 0.07 would be about 4. The question is referring to the answer of the two values Multiplied to each other.

To visualize the question, we have:

3.93 x 0.07

This would give us:

0.2751

Kerri would be correct if she was looking for the SUM of the two values.

This would be:

3.93 + 0.07

This would give us:

4

Therefore in trick problems like this ones, it is better to look at what exactly is being asked.
