Question

Jane has soccer practice every 5th day and tennis practice every 7th day. On which day will she have both soccer and tennis?

Answer 1

She will have soccer and tennis on the 35th day.

Explanation:

Now, you have to see a common number that you see in both 5 and 7. You should start out by listing the multiplication of both numbers like this up to like the 10th number of multiplication.

Multiplication of 5: 5, 10, 15, 20, 25, 30, 35, 40
Multiplication of 7: 7, 14, 21, 278, 25

So the least common number in both of these liens is 35 so it has to be the 35th day she will have both soccer and tennis practice.
