I don't now how to add pictures yet.
1.what is a good definition of a %?You should use words symbols. Pictures and numerical examples in your definition.
A Percent is a number out of 100. EXAMPLE=20% is 20/100
1.How are three fith's (3/5), 3:2, 60% and 0.6all the same ?n Use a picture and words to show your answer.
1/5=20% 1/5x3=60% 10=60 3:2 =part/part+whole= fraction 1/5=20% 1/5x3=60%
3.Show 3 different ways to find 35%of 80.
first we have to find what what 1% =80divided by 100 =8 so 1 = 8. (1%)x 35 =28 so 35% of 80 is 28.
4. Find a Link that deals with percentages. Leave a comment behind and add the link with a review.
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 is corret because there can be more children in M. Lowerys Class.
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?
b) What is 120% of 30?
A. 40%of 100 is 40
I got this answer by dividing 40 by 100 that gives me 0.4, and then you multiply the decimal by the part that gives you 40% of 16.
B. 120% of 100 is 120120/100=1.230 x 1.2=36120/100 = 36/30
I got this answer by finding out what 120%of 100 is and it is 100, and then I divided 120by 100which gives me 1.2.Then you multiply by the whole which is 30 by 1.2 and that gives you 30 out of 36
