Answers and explanations
| Question | Answer | Explanation |
|---|---|---|
| 1 | 432 | 36 × 10 = 360 and 36 × 2 = 72. 360 + 72 = 432. |
| 2 | 12 | 7 × 12 = 84, so 84 ÷ 7 = 12. |
| 3 | 7,501 | Add the columns from the right and regroup when a column reaches 10. The total is 7,501. |
| 4 | 3,543 | 2,457 + 3,543 = 6,000, so the difference is 3,543. |
| 5 | 5 | 6 × 7 = 42, and 47 − 42 = 5. |
| 6 | 5/8 | The bottom numbers match, so add the top numbers: 3 + 2 = 5, giving 5/8. |
| 7 | 0.3 | 3/10 means 3 tenths, which is 0.3. |
| 8 | 6 | The factors of 12 are 1, 2, 3, 4, 6 and 12. |
| 9 | 42 | 7 × 6 = 42. |
| 10 | 420 | 28 × 10 = 280 and 28 × 5 = 140. 280 + 140 = 420. |
| 11 | 168 | 24 × 7 = 168. |
| 12 | 6 | Half the perimeter is 15, which is length plus width. 15 − 9 = 6. |
| 13 | right angle | A 90 degree angle is a right angle, like the corner of a square. |
| 14 | 7,000 | The hundreds digit is 5, so round up to 7,000. |
| 15 | 1.2 | 7 tenths plus 5 tenths is 12 tenths, which is 1.2. |
Tips for Grade 4 math
- For multi-digit multiplication, break one number into tens and ones and add the partial products.
- Check division by multiplying the answer by the divisor and adding the remainder.
- List factors in pairs, such as 1 and 12, 2 and 6, 3 and 4, so none are missed.
