business people have determined 3/4 of items on a mailing list will change in one year, a business has a mailing list of 2728 people, after one year, how many address on that list will be incorrect, what is the answer
3/4 of 2728 = 0.75*2728 = 2,046 --> 2,046 of the addresses on that list will be incorrect.
3/4 of 2728 = 0.75*2728 = 2,046 --> 2,046 of the addresses on that list will be incorrect.
First, change 3/4 into a decimal.
$$3/4 = 0.75$$ You have to change 3/4 into a decimal so it can be easier to multiply.
Now, multiply 0.75 by 2,728.
$$0.75*2,728=2,046$$ So, 2,046 addresses will be incorrect.
