Mr Diaz's class in learning some new social studies vocabulary words. They already know the first 12 words from the unit. If they need to learn 30 words total and can learn 5 each week, how many weeks will it take them to be ready for the vocabulary quiz?

The answer to your question is: 3 weeks and 3/5 almost 4 weeks

Step-by-step explanation:

Need to learn 30 words

Already know 12 words

learn 5 words each week

# of weeks to be ready for the test

# of words need to learn = 30 - 12 = 18

Learn 5 words per week = 18 / 5

= 3 weeks and 3/5 almost 4 weeks
