The metric system is amazingly easy.
In this case all you have to remember that the prefix kilo means 1000
(e.g. 1 km = 1000 m, 1 kg = 1000 grams)
so for $10 Jackie can buy 10/5.8 kg
= 1.724 kg
= 1742 grams
In the US, a similar question might be
"Jackie goes to the store to buy some meat. The meat costs $3.80 per pound. How many ounces of meat could she buy for $10? "
- a much more complicated question.
Jackie goes to the store to buy some meat. The meat costs $5.80/kg. How many grams of meat could she buy for $10?
is there an easy way to do this? I did a few others like it, but kg and grams is not as easy
