simn spent 2/5 of his pocket money on a computer game
he spent 25% of his money on a ticket for a football match
what is the fraction of his pocket money that he had left
25% = 1/4
1/4 + 2/5 = 5/20 + 8/20 = 13/20
Kelly, Sarah or Holly, I lost track, I guess so did you.
All you need to do now is to subtract 13/20 from 100% to get what's left.
1/3 equals to 4/12, 1/4 equals to 3/12.
3/12 plus 4/12 equals 7/12. Therefore 5/12 left
To find the fraction of Simon's pocket money that he had left, we need to subtract the portions he spent from the total amount.
First, let's represent Simon's pocket money as a whole. We can assign a value of 1 to represent the total pocket money.
Simon spent 2/5 of his pocket money on a computer game. This means he has 1 - 2/5 = 3/5 of his pocket money left.
Next, Simon spent 25% of his money on a ticket for a football match. Since 25% is equivalent to 1/4, he spent an additional 1/4 of his remaining pocket money. Therefore, he has 3/5 - 1/4 = 12/20 - 5/20 = 7/20 of his pocket money left.
So, the fraction of Simon's pocket money that he had left is 7/20.
