Lesson Steps Head1
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Richard’s house is 7 km 300 m and Alex’s house is 11 km 432 m away from school. Whose house is far away and by how much? |
|
2 |
Clue |
Convert the distances from kilometers to millimeters (1 kilometer = 1,000,000 millimeters) |
|
3 |
Hint |
7 Km 300 m = 7.3 Km (Since 1Km = 1000 m)\$(300/1000 = 0.3)\$ Km So, 7 Km + 0.3 Km = 7.3 Km 11 Km 432 m = 11.432 Km (Since 1Km = 1000 m) \$(432/1000 = 0.432)\$ Km So, 11 Km + 0,432 Km = 11.432 Km |
|
4 |
Step |
Richard’s house is 7.3 kilometers away from school, so in millimeters: |
\$7.3 "kilometers" \times 1,000,000 "millimeters"/"kilometer" = 7,300,000 "millimeters"\$ |
5 |
Step |
Alex’s house is 11.432 kilometers away from school, so in millimeters: |
\$11.432 "kilometers" \times 1,000,000 "millimeters"/"kilometer" = 11,432,000 "millimeters"\$ |
6 |
Step |
So, in millimeters, Richard’s house is 7,300,000 mm away from school |
|
7 |
Step |
Alex’s house is 11,432,000 mm away from school. |
|
8 |
Step |
The difference in distance |
11,432,000 millimeters - 7,300,000 mm = 4132000 millimeters |
9 |
Step |
So, Alex’s house is farther from the school by 4,132,000 millimeters. |
