Final answer:
The mixture of paste includes 27 total parts, and at 135 milliliters total, each part is 5 milliliters. Therefore, the mixture contains 55 milliliters of glue.
Step-by-step explanation:
To determine how many milliliters of glue are in one mixture of paste, we first need to add up the total number of parts in the mixture: 12 parts plaster, 11 parts glue, 3 parts water, and 1 part vinegar gives us a total of 27 parts. Since one mixture of paste has a volume of 135 milliliters, we need to determine what volume corresponds to one part. We do this by dividing the total volume by the number of parts: 135 milliliters ÷ 27 parts = 5 milliliters per part. To calculate the volume of glue, we multiply the volume of one part by the number of parts of glue: 5 milliliters per part × 11 parts glue = 55 milliliters of glue.
