If we want to find the fraction of the total sum of pebbles james has, what we first might want to do is convert the previous sentences into equations.
00:18
So first it says peter has eight times as many pebbles as mary.
00:24
So that means peter has more than mary.
00:28
So we would want to do eight times the amount mary has to get what peter has.
00:33
So that would be p is equal to 8 times m.
00:38
So i'm just going to write up top here what these letters stand for.
00:42
Because it's always a good idea to define your variables.
00:46
So p is peter.
00:49
M is mary.
00:53
All right.
00:54
Next, it says mary has a third number of pebbles is james.
00:59
So mary has less pebbles of james, meaning we would want to take the amount that, james has and cut it in a third or divide it by three.
01:13
So then we'd have m is equal to one third the amount james has.
01:20
Then we can go ahead and say j is equal to james.
01:25
And then lastly it says james has double the amount of pebbles that jude has.
01:33
So whatever the amount jude has, we take or multiply, by two to get what james is.
01:41
So james is going to be equal to, well, we already use j.
01:44
So why don't we go ahead and say jude is d.
01:46
It's going to be two times d.
01:52
This is jude...
