A recipe for a bubble solution calls for 1/2 tablespoon of dishsoap for each batch . How many tablespoons of dish soap are needed to make 3 batches

Respuesta :

1/2 + 1/2 + 1/2 = 1 and 1/2 tablespoons
You need 1/2 a tablespoon for 1 batch
How many would you need for 3 batches? 

I would figure this out by multiplying 1/3 by 3:

.5 x 3 = 1.5

Your answer would be: 1 1/2 tablespoons of dishsoap for 3 batches
