To find the fraction of Mary's pocket money that she spent, we need to add the fractions representing the amount she spent on sweets and fruits.
Mary spent 3/5 of her pocket money on sweets and 1/2 on fruits.
To add fractions, we need a common denominator. The least common multiple of 5 and 2 is 10.
To convert the fractions to have a common denominator of 10, we can multiply the numerator and denominator by the same number.
For the fraction 3/5, we can multiply both the numerator and denominator by 2 to get 6/10.
For the fraction 1/2, we can multiply both the numerator and denominator by 5 to get 5/10.
Now we can add the fractions:
6/10 + 5/10 = 11/10
The fraction 11/10 represents the portion of Mary's pocket money that she spent. However, it is greater than 1 (a whole), which doesn't make sense in this context since it's asking for a fraction of her pocket money.
To simplify the fraction, we can divide the numerator by the denominator:
11 ÷ 10 = 1 remainder 1
So the simplified fraction is 1 1/10, which means Mary spent 1 and 1/10 (or 11/10) of her pocket money.
