Liula [17]

$\frac{84}{21}=4$

Therefore you need 4 batches of cupcakes if you want <u>every person to get one cupcake</u>.

This means you multiply the amount of salt <em>per batch</em> by the number of batches, to get the total amount of salt you need.
Each batch contains <em>1 teaspoon of salt</em> for 21 cupcakes. Multiply: $4\text{ batches of cupcakes}\times1\text{ teaspoon of salt}=4\text{ teaspoons salt}$ for the whole thing.
