Question

what is 44% of 80 round to the nearest whole number what do I do.

Answer 1

turns out to be 35.20

Answer 2

80 * 0.44 = 35.2

Answer 3

\[
1\% = 80 / 100 = 0.8 \\
4 \% = 1\% \cdot 4 = 0.8 \cdot 4 = 3.2 \\
40 \% = 1\% \cdot 40 =(1\% \cdot 4) \cdot 10 = (3.2) \cdot 10 = 32\\
40 \% + 4\% = 32 + 3.2 = 35.2

\]

Answer 4

Is that the answer.

Answer 5

35.2 is the answer, but I tried to show the way too hmmph

Answer 6

It is all whole numbers on my assignment.

Answer 7

I'm sure you could make it shorter. Just tried to show it the way I see it. you could calculate this in your head I guess.. not too complicated in this case.
Anyway, if that's not what you wanted then I apologize.

Answer 24

What do u mn by that.

Answer 25

reading

Answer 26

reading what.

Answer 27

Dam, some long responses.

Answer 28

Ok..
\[
100\% \div 5\% = 20 \\
5 \% = 100\% \div 20 = 12.5 \div 20 = 6.25 \div 10 = 0.625 \\
15\% = 5\% \times 3 = 0.625 \times 3 = \\
= (0.6 \times 3) + (0.02 \times 3) + (0.005 \times 3) = \\
= (1.8) + (0.06) + (0.015) = 1.875
\]

Answer 29

I don't understand it really good I can but I can't.

Answer 30

ok. let's simplify this. can you find \(1\%\) of 12.5?

Answer 31

I think so.

Answer 32

ok, what is it then? =]

Answer 33

really I don't know wat that is. but was that the right answer you wanted me to answer.

Answer 34

Do you know what a % means?

Answer 35

yes I know wat % this means.

Answer 36

I'm not trying to mock, i'm asking seriously.

Answer 37

I am sorry for doing that to you.

Answer 38

it's ok i don't mind.
Let's see. We know the WHOLE sum is 12.5 right? so we say that's our 100%. the 1% is therefore \(\frac{1}{100}\) of it. right?

Answer 39

right.

Answer 40

if we divide 12.5 by 100 what do you get then?

Answer 41

sorry but do you have a facetime.

Answer 42

No, sorry =(
Do you get what I mean though?
\[
12.5 \div 100 = \;?
\]

Answer 43

you should get 0.125 correct.

Answer 44

yes very good =]

Answer 45

thank you.

Answer 46

Now, we need to multiply that by 15 hehe to get from 1% to 15%

Answer 47

r u saying to multiply 15 by one.

Answer 48

it's abit ugly, but the cleanest way I know to do this is to simply break this number to parts:
\[
0.125 = \\
\quad\quad\quad\quad 0.1 + \\
\quad\quad\quad\quad 0.02 + \\
\quad\quad\quad \quad 0.005
\]

Answer 49

is that clear so far?

Answer 50

ok add that. Right

Answer 51

now, if we want to multiply our 1% (which is 0.125 remember!) then we do
\[
0.125 \times 15 = \\
\quad\quad\quad\quad 0.1 \times 15 + \\
\quad\quad\quad\quad 0.02 \times 15 + \\
\quad\quad\quad \quad 0.005 \times 15
\]

Answer 52

Could you solve each one of those?

Answer 53

alright.

Answer 54

Is it 1.875

Answer 55

yes =]

Answer 56

thank you very much.

Answer 57

sure no problem

Answer 58

do I round that.

Answer 59

are u a student or a teacher.

Answer 60

Do they ask you to?

Answer 61

well, neither.

Answer 62

yes.

Answer 63

what are u than.

Answer 64

Well, they say to 'nearest cent'. a cent is a $0.01 right? so \(1.875 \to 1.87 \)

Answer 65

it could be \(1.875 \to 1.88\). it's actually more common to round 5 up..

Answer 66

right.

Answer 67

U r correct on the spot great job.
