clueless mum
Hello, Kelly!
Are you sure of the wording of this problem?
It's not reasonable at any level ... certainly not for a sixth grader!
We can not convert liters into pints by pouring water back and forth.You have a 3-liter jug and a 5-liter jug.
How can you measure 7 pints in one jug?
You can only use the two jugs.
. . . . . . see?
Hello again, Kelly!
A strange way to state the problem.
It's both confusing and untrue . . . very misleading.
This is a classic (old) problem.
We have a 3-liter and 5-liter jug.
And we wish to measure 4 liters.
Fill the 3-liter jar.Code:* * | | * * | | |:::::| | | |::3::| | | |:::::| | | * - - * * - - * 3 5
Empty the 3-liter jar into the 5-liter jar.Code:* * | | * * | | | | |:::::| | | |::3::| | | |:::::| * - - * * - - * 3 5
Fill the 3-liter jar.Code:* * | | * * | | |:::::| |:::::| |::3::| |::3::| |:::::| |:::::| * - - * * - - * 3 5
Empty the 3-lliter jar into the 5-liter jar
. . until the 5-liter jar is full.Code:* * |:::::| * * |:::::| | | |::5::| | | |:::::| |::1::| |:::::| * - - * * - - * 3 5
Empty the 5-liter jar.Code:* * | | * * | | | | | | | | | | |::1::| | | * - - * * - - * 3 5
Empty the 3-liter jar into the 5-liter jar.Code:* * | | * * | | | | | | | | | | | | |::1::| * - - * * - - * 3 5
Fill the 3-liter jar.Code:* * | | * * | | |:::::| | | |:::::| | | |:::::| |::1::| * - - * * - - * 3 5
Empty the 3-liter jar into the 5-liter jar.Code:* * | | * * |:::::| | | |:::::| | | |::4::| | | |:::::| * - - * * - - * 3 5
. . . . . . . . There!

Hello, Kelly!
I'll do the first of these.
1) We have a 1.75-pint jug and a 1- pint jug.
We want to measure a half-pint.
Fill the 1-pint jug.Code:* * | | | | * - - * | | |:::::| | | |::1::| | | |:::::| | | *-----* *-----* 1 1.75
Empty the 1-pint jug into the larger jug.Code:* * | | | | * * | - - | | | |:::::| | | |::1::| | | |:::::| *-----* *-----* 1 1.75
Fill the 1-pint jug.Code:* * | | | | * - - * | - - | |:::::| |:::::| |::1::| |::1::| |:::::| |:::::| *-----* *-----* 1 1.75
Pour the 1-pint jug into the larger jug
. . until the larger jug is full.Code:* - - * |:::::| |:::::| * * |:::::| | | |:1.75| | - - | |:::::| | 0.25| |:::::| *-----* *-----* 1 1.75
Empty the larger jug.Code:* * | | | | * * | | | | | | | - - | | | | 0.25| | | *-----* *-----* 1 1.75
Empty the 1-pint jug into the larger jug.Code:* * | | | | * * | | | | | | | | | - - | | | | 0.25| *-----* *-----* 1 1.75
Fill the 1-pint jug.Code:* * | | | | * - - * | | |:::::| | | |::1::| | - - | |:::::| | 0.25| *-----* *-----* 1 1.75
Empty the 1-pint jug into the larger jug.Code:* * | | | | * * | - - | | | |:::::| | | |:1.25| | | |:::::| * - - * * - - * 1 1.75
Fill the 1-pint jug.Code:* * | | | | * - - * | - - | |:::::| |:::::| |::1::| |:1.25| |:::::| |:::::| * - - * * - - * 1 1.75
Pour the 1-pibnt jug into the larger jug
. . until the larger jug is full.Code:* - - * |:::::| |:::::| * * |:::::| | | |:1.75| | - - | |:::::| |:0.5:| |:::::| * - - * * - - * 1 1.75
. . . . . . . . . . There!
The second problem takes 16 steps.
But, by now, you should be able to work it out yourself.
