Amanda can finish writing 6 thank-you notes in the 2/3 of an hour she has left. To find this, we divide the total time she has left by the time it takes her to write each note. This is a division of fraction's problem.
Step-by-step explanation:
The subject of this question is fraction word problems. Amanda has 2/3 of an hour left to write thank-you notes. Each note takes her about 1/9 of an hour to write. To find out how many notes Amanda can write, we divide the total amount of time she has left (2/3) by the time it takes to write each note (1/9).
When you divide fractions, you actually multiply by the reciprocal of the divisor. So, 2/3 divided by 1/9 is equal to 2/3 multiplied by 9/1. This equals 18/3, which simplifies to 6 notes. So, Amanda can complete 6 thank-you notes in the time she has left, making the answer c) 6 notes.
