@ZeHanz

Answer 1

do you know how to do it

Answer 2

No :(

Answer 3

1. First, calculate the part between the brackets, then multiply with 1/10, finally add 3.

Answer 4

how do i multiply 10 to 1/10?

Answer 5

suppose you have a cake sliced in 10 pieces. Then every piece is 1/10 of the cake.
What do you get when you are offered 10 pieces?

Answer 6

a whole?

Answer 7

ohhhhhhhhhhhhhhhhhh

Answer 8

Mind=blown

Answer 9

now can you explain it with the decimal :(

Answer 10

#3? Seems difficult until you realize the denominator is twice the numerator...

Answer 11

Huh?

Answer 12

Look at it:
numerator: .18
denominator: .36.

That is twice as much.

Here are some examples: 3/6, 100/200, 2/4, 7/14

Everytime this really is the same number!
It is also the same number when you have .18/.36

Do you see what number it is?

Answer 13

so it would be 2?

Answer 14

You wouldn say 3/6 is equal to 2, now would you?

Answer 15

Im so confused *-*

Answer 16

\[\frac{1}{100}=.01\]
\[\frac{1}{10}=.1\] using these you can make up what each decimal is actually in fractions

Answer 17

so for .18 you have

\[\frac{1}{10}+\frac{8}{100}\]

Answer 18

If you had 3 parts out of 6 how much would you have?

Answer 19

1/2

Answer 20

Yes! so just like the other fractions I mentioned, .18/.36 is also 1/2

Answer 21

so im stuck on number 2

Answer 22

i dont understand how to multiply 12/30 by 30

Answer 23

Sorry, going to sleep now...

first do 5*6
then 12/30 * that outcome
then+3

Answer 24

mhmmk bye

Answer 25

is 2 this

\[\frac{12}{30}*(5)*(6)+3\]

Answer 26

yes

Answer 27

OK last one: see it another way: youhave 12/30 * 30

So you have 12, then you divide by 30, then you multply with 30. What do you get ?

Answer 28

divide 12 by 30?

Answer 29

Yes and directly after that *30...

Answer 30

12?

Answer 31

Yes!, the operations cancel!

Answer 32

look at is as this

\[\frac{12}{30}*\frac{30}{1}\]

this is the same as
\[\frac{12}{1}*\frac{30}{30}\]...
\[\frac{30}{30}=1\]

Answer 33

Bye

Answer 34

so you're left with \[12\]

Answer 35

so the answer would be 12. Mhmmk

Answer 36

yep in other words if you are multiplying two things and you have the same number in the numerator and denominator you can cancel them since they will equal 1

Answer 37

then for the last one? .8/.40=?
how do i do that
