Answer:
She will jog and lift weights on the same day in 10 days
Step-by-step explanation:
To find when two events will happen on the same day, we find the least common multiple(that is not 0) of their frequencies.
In this question:
Every two days she jogs
Every 5 days she lifts.
Multiples of 2: {0, 2, 4, 6, 8, 10, 12, ...}
Multipled of 5: {0, 5, 10, 15, ...}
The least common multiple is 10, so:
She will jog and lift weights on the same day in 10 days
