21. Melanie is making homemade stickers. She uses the recipe shown to create the glue for the stickers.
a. She has 545 milliliters of vinegar. Which is a more
reasonable estimate for the number of batches she
can make, 5 or 7? Explain your answer.

b. About how many times as many milliliters of vinegar are needed than
lemon extract?

a) 5 b) 8 times

Step-by-step explanation:

a) Because the recipe requires 112 millimeters of vinegar, it is simpler to round it to the nearest 10th or 100th when estimated, in this case being 110, or 100. We know that Melanie has 545 millimeters of vinegar and it takes around 110 millimeters to make one batch. 110x5= 550, 110x7=770. Which one is closer to 545? 550 or 770? 550!

b) There are 14mL of lemon extract to make one batch, and 112mL of vinegar. You can divide 112 by 14 to get how many times more vinegar there is in comparison to lemon extract. 112 divided by 14 is 8!
