Last summer Miss Lewis was in Europe. She spent:
1 week and 3 days in Spain,
1 week and 2 days in Italy,
2 weeks and 5 days in France,
3 weeks and 4 days In England,
1 weeks and 6 days In Scotland.
How many weeks and days was Miss Lewis in Europe?

9 weeks and 4 days

Step-by-step explanation:

We know that all of these countries are in Europe, and that there is 7 days in a week. In the following steps, I will multiply the number of weeks by 7 and add the product to the number of remaining days.

Spain: 1 * 7 + 3 = 10

Italy: 2 * 7 + 5 = 19

France: 3 * 7 + 4 = 25

Scotland: 1 * 7 + 6 = 13

Now, I will add all of the results together. 10 + 19 + 25 + 13 = 67.

Now, I will divide 67 by 7 and only use the whole number on the left side of the decimal point to get 9.

Now, I will multiply 9 by 7 to get 63. The remainder is 4 days. So, Miss Lewis was in Europe for 9 weeks and 4 days.

P.S.: It sounds complicated, but all I really did on the last 2 steps was divide and find a remainder, which is very simple.
