Bob spends 3/8 of his pocket money on food and 1/3 of it on a present for his sister. What is the fraction of his pocket money remains?
I need some help on this!

= 1 - 3/8 - 1/3
= 24/24 - 9/24 - 8/24
= 7/24
To find the fraction of Bob's pocket money that remains, we need to subtract the fractions he spent on food and the present from 1.
First, let's calculate the fraction Bob spent on food. He spent 3/8 of his pocket money on food.
So, the fraction Bob spent on food is 3/8.
Next, let's calculate the fraction Bob spent on the present. He spent 1/3 of his pocket money on a present for his sister.
So, the fraction Bob spent on the present is 1/3.
Now, to find the fraction of his pocket money that remains, we subtract the sum of the fractions he spent on food and the present from 1.
1 - (3/8 + 1/3)
To simplify, let's find a common denominator for 8 and 3, which is 24.
(24/24) - (9/24 + 8/24)
Now, we can subtract the fractions:
(24 - 9 - 8) / 24
7/24
Therefore, the fraction of Bob's pocket money that remains is 7/24.
To find the fraction of Bob's pocket money that remains after spending on food and a present for his sister, we need to subtract the amount spent from the total pocket money.
Let's calculate it step by step:
1. Convert the fractions to have a common denominator:
Since 8 and 3 are the denominators of 3/8 and 1/3 respectively, let's find the least common multiple (LCM) of 8 and 3, which is 24.
3/8 = (3/8) * (3/3) = 9/24
1/3 = (1/3) * (8/8) = 8/24
2. Combine the fractions:
Now that both fractions have the same denominator, we can add them together:
9/24 + 8/24 = 17/24
3. Subtract the combined fraction from 1:
Since we want to find the fraction that remains, subtracting the combined fraction from 1 will give us the answer:
1 - 17/24 = (24/24) - (17/24) = 7/24
Therefore, the fraction of Bob's pocket money that remains is 7/24.
