Calculating Glue and Glitter Quantity for 4 Bottles of Glitter Glue

Explanation:

To determine how much glue and glitter Gary would need to make 4 bottles of glitter glue, we need to perform a multiplication operation based on the given quantities for 1 bottle. For 1 bottle, Gary uses 3.8 ounces of glue and 1.9 ounces of glitter.

So, for 4 bottles, we multiply these quantities by 4:

Glue: 3.8 oz × 4 = 15.2 oz

Glitter: 1.9 oz × 4 = 7.6 oz

Therefore, Gary would need 15.2 ounces of glue and 7.6 ounces of glitter to make 4 bottles of glitter glue.
