Question 1

A percent is a fraction out of 100

Question 2

Question 3

This is a post about percents and chuck noris.

Question 5
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's class has 50% of children who seen their ready goal. 50% is half of a 100%.

Ms. Lowrey's class has a 55% of children that have seen their reading goal for the month. 55% is not half of 100%. What i did was i divided 55 by 2 and it equaled to 27.5 but i think Ms. Stanzi's guess was right.

50% out of 100

Question 6
Use a hundred grid (unit square) to illustrate the following questions. Once you have explained and illustrated what the question means solve it.

a) 16 is 40% of what number?
a) 80

16 / 0.4 = 40
40 / 100 = 0.4

b) What is 120% of 30?

b) 30
120 / 10 = 1.2 30 x 1.2 = 36 36 x 100 = 3600 36000 / 30
