Question

Find C intersection D.
C: {3, 6, 9, 12, 15, 18}
D: {numbers divisible by 2 from 1 to 20}

{2, 4, 6, 8, 10, 12, 14, 16, 18, 20}

{6, 12, 18}

{2, 3, 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20}

{ }

Answer 1

Look at all the numbers in C and compare them to numbers in D. For example 3 is not divisible by 2, 6 is, 9 is not, 12 is, 15 is not, 18 is .

C intersection D = {6, 12, 18}
