Math word problems

Here's a good one:bigear:

 

 

"Jason and Bob have 193 marbles altogether. Bob has 47 marbles fewer than Jason. If Jason gives 15 marbles to Bob, how many more marbles will Jason have than Bob?" – CWP 3 (original edition #19 pg.10)

Before the difference is 47. After Jason gives 15 marbles to Bob the amount will change by 30 (that is Bob's count will go up by 15 and Jason's count will go down by 15 = net change of 30 marbles.)

 

47-30 = 17

 

Now Jason has 17 more marbles than Bob.

Ray we are working on CWP3 this morning as well.

 

We are doing problem 20 on page 103 which is an equally awesome problem.

Hi, Snickerdoodle,

 

I'm not sure if you wanted a solution or not, but here is mine:

 

Note: [ ] = unit

 

Rachel: [ ][23][42]

 

Jane: [ ][23]

 

Sandy: [ ]

 

We are given that the total pencils for all three = 124.

 

Therefore: 3 Units = 124-23-23-42 = 36

 

Which implies: 1 unit = 12 pencils

 

So: Sandy has 12 pencils. And Rachel has 12+23+42 = 77 pencils.

 

Together they have 89 pencils.

 

Hope that helps. :)

Snickerdoodle, way to make hay! :patriot:

We are just now getting into CWP3 challenging problems, and for us they have more oomph than the problems of the first two books- no contest.

 

Fractalgal thanks for the solutions, :thumbup:

 

Mommy4ever we are not batting a thousand here either, but its good fun;)

What's "CWP"?

 

These are some awesome word problems... :)

This is just like Singapore word problems!

 

Jason and Bob's marbles = 193 - 47 less that Bob has = 146, so each of them have 73 (half of 146) and Jason also has 47 more (73 + 47 = 120).

 

Jason has 120 and Bob has 73 marbles.

 

If Jason gives 15 marbles to Bob (120 - 15 = 105), then Bob will have 88 marbles (73 + 15 = 88).

 

So, 105 - 88 = 17

Jason has 17 more marbles than Bob after giving him 15.

CWP is "Complex Word Problems." To confuse matters there is a well-loved edition (the one Ray is using) that went out of print, and a "new" edition (totally different) that was just released recently and has not been much reviewed here yet.

Are you talking about Singapore's Challenging Word Problems, or are these different books? Please don't tell me they're different books..... because then I'd have to go look at them. :blink:
