#1**+5 **

Only because you do not know how to do them yet. :)

say Tom and Jane have marbles in the ratio 4:5 and Jane has 30 marbles.

Let's see what info we can get from that.

I think it is much easier to set up a box like this. :)

Tom | Jane | Total |

4 | 5 | 4+5=9 |

4*6=24 So Tom has 24 marbles | 30 Now 30 divided by 5 is 6 so 5 so if I multiply the others in this row by 6 I will have everything | 9*6=54 so altogether there are 54 marbles. I can check this by adding Tom's and Jane's marbles together 24+30=54 great it must be correct |

this is the EASY way to do it :)
