Question

Is it a set(multiplies of 5 less than 30)and why

Answer 1

Answer:

Positive multiples of 4 less than 30 are P={4,8,12,16,20,24,28}

Positive multiples of 6 less than 30 are Q={6,12,18,24}

Intersection of P and Q will be

P∩Q={12,24}

Count of numbers is 2 in intersection of P and Q.

Step-by-step explanation:

The multiples of 5 include 5, 10, 15, 20, 25, 30, 35, 40,…. The multiples of 10 include 10, 20, 30, 40, 50, 60,…. Thus, the common multiples of 5 and 10 are 10, 20, 30, 40,…. That means all the multiples of 10 will be the common multiples for 5 and 10.
