Question

Hailey paid $13 for 1 3/7 kg of sliced salami. What was the cost per kilogram of salami?

Answer 1

first lets get the total weight that Hailey bought, that is working with fractions:
1 3/7 = 7/7 + 3/7
= 10/7 = 1.43
so we use a rule of three to solve this:
1.43 kg ------> $13
  1 kg  --------> x
x = (1)(13)/(1.43)
x = 9.09
therefore a 1kg of sliced salami costs $9.09
