Let's consider 2 lemons a "batch." So you can get one batch for 15 cents, and you have 60 cents to spend. To find out how many batches you can get with 60 cents, divide 60 by 15 to get 4. Now to get the total number of lemons, multiply the number of batches (4) by the number of lemons in each batch (2) which will give you a total of 8 lemons.
If 2 lemons cost 18 cents then 1 lemon would equal 9 cents. So you know 1=9 and 5=x make a ratio 1 5 1\ /5 - = - Do cross products - - 5 x 5 / \x So... 1x=25= 1x/1 and 25/1 x=45 They cost 45 cents
