What is LCM of two numbers?
"It is a number that is divisible by the two given numbers."
For given question,
Jim has 100 cards there is a whole number from 1 to 100 on each card.
He puts a star on every card has a multiple of 3 on it and puts a circle on every card that has a multiple of 7 on it.
We need to find the numbers on the cards that have both a star and a circle on them.
This means, we need to find the numbers which are divisible by 3 and 7.
This means, the required numbers are divisible by the LCM of 3 and 7.
The LCM of 3 and 7 is 21.
So, the required numbers are multiple of 21.
From 1 to 100, the numbers which are multiple of 21 are 21, 42, 63, 96
Therefore, the numbers on the cards that have both a star and a circle on them are 21, 42, 63, 96
