Question

Sara's having a barbecue and she cooks burgers. She buys a 6 pack of breadrolls and a 10 pack of burger meat. How can sara get the same amount of burger to bread rolls

Answer 1

Buying 5 packs of bread rolls and 3 packs of burger meat

Explanation:

Sara needs to find the least common multiple between 6 bread rolls and 10 pieces of burger meat:

`LCM:\\10\ 6\ |2\\5\ \ 3\ |3\\5\ \ 1\ |5\\1\ \ 1\ |1\\\\LCM = 2*3*5=30`

Sara will get the same amount of burger to bread rolls when she buys 30 units of each. The numbers of packs of each product that she must buy are:

`B=(30)/(6)=5\ packs\\ M=(30)/(10)=3\ packs`

Sara should buy 5 packs of bread rolls and 3 packs of burger meat.
