Word Problem

Find the Error/random

100

Find the error in my work:

Explain what I did wrong and then tell me the correct answer:

8 x 23 = 8 (2+3)
          = (8 x 2) + (8 x 3 )

          = 16 + 24

          = 40

I did not split my 23 properly. I should've times 8 by 20 and 3. That would have led me to the answer of 184.

200

Find my error:

9 x 75 = 9 x (7 + 5)

          = (9 x 7) + 5

          = 63 + 5

          = 68

I did not distribute my 9 to both numbers. If I did, I would've had 9x7 plus 9x4, and then I would've gotten 675.

Explain how you know a number is prime and how you know a number is composite. Give an example for both. 

I know a number is prime because it only has two factors (3)

I know a number is composite because it has more than 2 factors. (9) 

400

Give me the first 7 multiples of 4

4, 8, 12, 16, 20, 24, 28

Miss Flynn is organizing supplies for her classroom. She buys 24 boxes of pencils. Each box has 36 pencils inside.
Later, she decides to share the pencils equally among 8 groups of students.

How many pencils does she buy? 

How many does each group get?

24 boxes × 36 pencils each
= 864 pencils 

864 ÷ 8 groups
= 108 pencils per group
