Selena is finding 20 × 160. Explain why she can think of 20 × 160 as 2 × 10 × 16 × 10. |
| |
|
A. |
20 = 2 × 10 and 160 = 16 × 10, so 20 + 160 = 2 × 10 + 16 × 10 |

20 = 2 × 10 and 160 = 16 × 10, so 20 × 160 = 2 × 10 × 16 × 10 |

C. |
20 = 2 × 10 and 16 = 16 × 100, so 20 × 160 = 2 × 10 × 16 × 10 |
D. |
20 = 2 + 10 and 160 = 16 + 10, so 20 × 160 = 2 + 10 × 16 + 10 |
