Caroline is making some table decorations.
each decoration is made from a candle and a holder.
caroline buys some candles and some holders each in packs.
there are 30 candles in a pack of candles.
there are 18 holders in a pack of holders.
how many packs of candles and how many packs of holders does caroline buy?

there are 8 candles

Step-by-step explanation:

(i) In order to obtain an equal amount of candle to candle holders Caroline has to buy enough packs to obtain a 1:1 ratio.  

Therefore to obtain a 1:1 ratio:

=30 candles/18 candle holders * (18/30)

Therefore she needs to buy 18 packs of candles and 30 packs of candle holders to have exactly the same number of candles and holders

(ii) Caroline can make = 30*18 = 540 table decorations
