The trial and error way--not very mathy.
56 x what number ends in a 0.
56 x 1 = no
56 x 2 = no
56 x 3 = no
56 x 4 = no
56 x 5 = 280 and 280/40 = 7
5 packets of 56 = 280 lemon sweets
7 packets of 40 = 280 minty sweets
Minty sweets are sold in packets of 40
Lemon sweets are sold in packets of 56.
Andy wants to buy the same numbers of Minty sweets and lemon sweets.
What is the smallest number of packets of each type of sweets he could
buy?
