Miguel bought a ¾ pound bag of chocolate chips. He used ⅘ of the bag in his chocolate chip cookies. How many pounds of chocolate chips did he use?

Convert to percentages to understand the question better:

3/4 = 75%

4/5 = 80%

What is 80% of 75%?

Convert the percentages to decimals:

75% = 0.75

80% = 0.8

Calculate:

0.8 × 0.75 = 0.6

Convert back to original problem's format (fraction):

0.6 = 60% = 6/10 = 3/5

Miguel used 3/5 pounds of chocolate chips.

the correct is answer is a 9-sided polygon!
