Percentages

Hello, today we were working on percentages in class.

Although percentages are difficult for a lot of people, if you understand the basics, you’ve already made amazing progress.

these are the two questions my group and I had to answer:

Now the hard part is actually working out the answer.

Question 1:

 How might Jess finish to find 35%?

First, we must calculate 10% of 150, which is simpler because it is a standard percentage and equals 1/10 of 150.

1/10 of 150 Equals 15

Now that we need to reach 30%, we must multiply 15 by 3.

15 × 3 = $45

The final 5%, which can be calculated by halving 15 now, is added.

Half of 15 equals $7.50

We now need to multiply $45 by $7.50.

$45 + $7.50 = $52.50

However, $52.50 is not the correct response, thus we must subtract $52.50 from $150 to arrive at the correct response.

$150 – $52.50 = $97.50

Our answer is $97.50.

(The answer is different depending on which school you attend)

Question 2:

How else could you find 35% of $150?

I’m not going to answer this question right now because I’m a little lost on it, but I will do so tomorrow along with the solution.

 

 

 

 

 

 

Math

Hello, so in Hurumanu we have been doing measurement and columns (technically I don’t have to do a blog post but I’m setting a goal for myself to upload more frequently) Anyways here’s what I have been doing in math.

Example:  of how to use column to subtract. ( I hope that made sense please comment if it doesn’t😲)

The answer would be 33 here’s why:

as you can see you can’t take zero away from seven so you need to borrow from the column next to it  but as you can see you can’t borrow from it cause it has nothing as well so we borrow from the column next to it so let’s give one to the second column and the two now becomes a one and so now we need to give one to the first column and now the ten becomes a nine (because it’s the ten’s column) and so the seven becomes a ten and so now you can finally complete the questions.

10-7=3

9-6=3

1-1=0

so the answer is 33
