1.       If one number divides exactly into another with no remainder, we say the second number is a multiple of the first number Eg.   6 divides exactly into 12, therefore 12 is a multiple of 6.        5 divides exactly into 45, therefore 45 is a multiple of 5.  2.      Which of these statements are true and which are false? (put a tick mark for true and cross for false) a) 16 is a multiple of 4                              b) 42 is a multiple of 7 c) 15 is a multiple of 2                              d) 100 is a multiple of 3 e) 40 is a multiple of 4 and 10                f) 27 is a multiple of 3 and 9 2. Write three multiples of 7 smaller than 50.    ______________________________ 3.   Circle the multiples of 6.     -    23,     50,         48,         24,         67,         30,                    42 4.   Circle the factors of 45.       -    9,       90,         180,       7,            1,            15,                    3,        5 5.   Write a
