## Answers and Explanations

1. A: If there are 7 pens with 3 cattle, then the total number of cattle is found by 7x3=21, not 20. In the other problems, 8x3=24,3x8=24, and 3x7=21.

2. B: The cost of one eraser is found by dividing the total cost by the number of erasers. Since the cost of the erasers is $4.50, and there are 18 erasers, the expression for the cost of the eraser will be $4.50x18=$0.25. The total cost of one eraser is $0.25

3. C: If Raquel had 36 stamps and divided them into 9 groups, there will be 4 stamps per group because 36x9=4. She then adds 2 stamps to each group so that she has 6 stamps per group. Since there are nine groups of six and 9x6=54, she has a total of 54 stamps. If she gives 4 stamps each to 13 friends, she gives away 4x13=52 stamps. This means she has 54-52=2 stamps left over.= 13 r 2, so she gave four stamps to each of her 13 friends and had a remainder of 2

4. C: One number is the factor of another if it will divide it with no remainder. Ten is not a factor of twelve because 12x10=1 remainder 2. Also, ten is not a factor of twenty-four because 24x10=2 remainder 4. Six is not a factor of eighty because 80x6=13 remainder 2. The correct answer is sixty, because 4, 6 and 10 all divide it evenly.

5. D: The first figure had 6 sides. The second figure has 11 sides because 5 sides had to be added to make the next figure. This pattern of adding 5 segments continued, so the answers had to be 6, 11, 16, and 21.

6. D: 90x10=900, so 900 is 10 times greater than 90. 800 is 100 times greater than 8, 3000 is 100 times greater than 30, and 70 is only a tenth of 700. Therefore the only answer is D.

7. B: The value of A is 5,032,080; the value of C is 5,320,008; and the value of D is 5,328. B shows 5,320,080 which is the original number.

8. D: The 8 is in the hundreds place, and because the number to the right of 8 is a five, the 8 must round up to a 9. The remaining numbers change to a 0. Therefore the answer is 7,900.

9. B: Adding the ones place, you get 10, so the one carries to the tens place. 1+8+5=14, so the 4 goes in the tens place and the 1 is carried over the hundreds place. 1+4+3=8, so the 8 goes into the hundreds place. The final answer is 840.

10. C: To subtract the ones column, a 1 has to be borrowed from the tens column, so the 0 becomes 10 and the 5 becomes a 4. 10-7=3, so the 3 goes in the ones unit. To subtract the tens column, a 1 needs to be borrowed from the 2 in the hundreds column. That 2 becomes 1 and the 4 in the tens column becomes 14. 14-8=6, so the 6 goes in the tens column. Finally the 1 is borrowed from the thousands column so that 1 becomes 0 in the thousands column and the 1 in the hundreds column becomes 11. 11-4=7 so the 7 goes in the hundreds place of the answer. The final answer is 763.
