What is a good Definition of percent?? .

A Percent is a number out've 100

It can be converted into a decimal, fraction, or ratio

example-(80%)

fraction-80/100

decimal-0.8

ratio-80:20

How are three fifths(3/5), 3:2, 60% and 0.6 all the same??

They are all equivalent to each other

The reason why 3/5, 3:2, 60%, and 0.6 are all are the same or equivalent to each other is because, if u try to convert 3/5 into a decimal, you'd get 0.6. The way to get 0.6 is that you divide the numerator(3) by the denominator(5) and you'd get 0.6. If you converted 0.6 into a percent, you'd get 60%, this is because percent is out of 100 and in this case we've got 60% and 0.6 x 100= 60.

Finally if u convert 3/5 into a ratio, it would be expressed as 3:2 because the numerator (3) is put as the first part of the ratio which which is also 3 and than to get the second part of the right side of the ratio, you subtract the denominator (5) by the numerator (3) - (5-3=2) and you get the second part of the ratio and in this case the second part would be 2. The equivalent ratio for 3/5 would be 3:2

What are 3 different ways to find 35% of 80?

35%/100=0.35 x 80=28

80/4=20 or 25% 80/10=8 or 10% 20+8=28 or 35%

80/100=0.8 or 1%x35= 28

Find a link to blogs that deal with percentages. Leave a comment behind and add the link with a review (What the post was talking about....yes you have to read the post and why others should read the post) Hint In the side bar there are links to other schools. Three of them have done work on percentages!

you should look at this site because it explains percents using money and it might help you understand percents more?

The principal announced that 50% of the children in Ms. Stanzi's class met their reading goal for the month and that 55% of the children in Ms Lowrey's class met their reading goal for the month. Ms Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not.

Ms. Stanzi have 200 students and Ms. Lowrey only have 100, Ms. Stanzi would have more students who mer their reading goal.

Stanzi= 200 / 2 =100 or 50% 100 students met their reading goal in here

Lowrey= 100 / 100 = 1 x 55 = 55 or 55% 55 students met their reading goal in here.

Use a hundred grid (unit square) to illustrate the following questions. Once you have explained and illustrated what the question means solve it.

Got images on here but wouldnt upload onto blog.
