Kala's penny bank is 2/3 full. After she removes 80 pennies, it is 1/2 full. How many pennies can Kala's bank hold?

Answer 14

call the unknown amount of gallons in a full bucket "x"

they say 1/10 full

1/10 full is 1/10 of x or 1/10 * x
or x/10

ok so far?

we want to know how many pennies. Call that amount "x"

do you know how to write
2/3 of that amount ?

Answer 19

2/3 of x? I don't have the number how can I write 2/3 of it

Answer 20

Kala's penny bank is 2/3 full.

you want to write 2/3 of what ? (what letter do we use?)

yes you write 2/3 of x
which means 2/3 times x
or just
\[ \frac{2}{3} x \]

Answer 21

This is why math makes absolutely no sense to me sorry haha I just want to know the formula so I can do the other problems

Answer 22

OH okay

Answer 23

It is a way of thinking, and the only reason to do these is to learn how to think this way.
It's like learning to read... hard until you "get it", then it's useful.

anyway

she removes 80 pennies,

that means you have
2/3 x
and you take away 80

how do you write "take away 80" hint: add or subtract 80?

Answer 24

Subtract

Answer 25

if it is not clear, how would you do:
you have 100 and take away 80
how do you write that problem ?

Answer 26

you have 100 and take away 80

you would write
100 - 80

your problem is
you have 2/3 x and take away 80

how do you write that ?

Answer 27

type faster or it will time out

Answer 28

2/3 x - 80

Answer 29

bank is 2/3 full. After she removes 80 pennies, it is 1/2 full.

that says after you subtract 80 you have 1/2 full. How do you write 1/2 of "full"
you write 1/2 x

so the problem is
2/3 x - 80 = 1/2 x

to solve this, add -1/2 x to both sides
2/3 x - 1/2 x -80 = 1/2 x - 1/2 x
now simplify the right side to zero
2/3 x - 1/2 x -80=0

now add +80 to both sides

can you do that ?

Answer 30

Sorry had to go in the shower, there's no way to just plug in the numbers to an equation and figure it out from there?? Is all this work really necessary?

Answer 31

yes, this is how you do this problem.
