Answer:
9 batches of cookies
Step-by-step explanation:
Mara bought a bag that contained 16
cups of sugar. She uses 2/3 cup of
sugar each time she makes a batch of
cookies.<em> If the </em>bag now has 10 cups <em>of
</em>
<em>sugar </em>left<em>, how many </em>batches of cookies<em>
</em>
<em>has she </em>made<em>?</em> (Show equation)
Well, if the bag originally had 16 cups and now it has 10 cups, then you have to subtract 10 from 16 (16-10). 16 - 10 = 6 cups used. Now you have to divide 2/3 from 6 (6 ÷ 2/3). 6 ÷ 2/3 = 9 batches of cookies.
