i) G = {all the factors of 20}

Question

List the elements of the following sets.

i) G = {all the factors of 20}

ii) F = {the multiples of 4 between 17 and 61 which are divisible by 7} 

iii) S = {x : x is a letter in the word ‘MADAM’} 

iv) P = {x : x is a whole number between 3.5 and 6.7}

Answer 1

i) G = {1, 2, 4, 5, 10, 20} 

ii) Multiples of 4 between 17 and 61 x = {20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60} F = {28, 56} 

iii) S = {M, D, A} 

iv) P = {4, 5, 6}
