- A500
- B700
- C60
- D70
- E600
Q2:
Yara, Mariam, and Nada went to a restaurant for dinner. The bill of their meals amounted to 207 pounds. Estimate how much each of them had to pay if they shared the cost of the bill equally between them.
Q3:
Estimate the quotient of the following operation: .
Q4:
Bassem has made a table of multiples of 6. Help him use the table to estimate .
| Number | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 |
|---|---|---|---|---|---|---|---|---|
| Multiple of 6 | 42 | 48 | 54 | 60 | 66 | 72 | 78 | 84 |
Find the missing multiples of 6 to finish the sentence:
70 is between and .
- A72, 78
- B60, 66
- C66, 72
- D54, 60
- E78, 84
So, is about .
Hint: Which multiple of 6 is it closest to?
Q5:
