From th question, we were told that:
The Cameron family spends 3/10 of their budget on groceries.
They also spend another 3/10 going out to eat.
We are asked to find the fraction of the budget they spent on food altogether.
If 3/10 is spent on groceries which can be termed as food
And Another 3/10 spent going out to eat.
Hence, the fraction of the budget spent on food altogether is:
3/10 + 3/10
= 6/10
= 3/5
Therefore the fraction of their budget spent of food altogether is 3/5.
