Let antonio's age = a and let sarah's age = s
2a + 3s = 34 (given in question)
s = 5a (given in question)
Because we know that s = 5a, we can replace it with 5a in the first equation to give this:
2a + 3(5a) = 34
∴ 2a + 15a = 34
∴ 17a = 34
∴ a = 2
Therefore we can see that Antonio is 2. Because we have been told that Sarah is 5 times Antonio's age, we can say that Sarah is 10.
Answer:
Proportion states that the two ratios or fraction are equal.
As per the given statement: For every 3 ounces of peanuts, there are 2 ounces of cashews. A batch has 60 ounces of peanuts.
Let x be the ounces of cashew will a batch have.
then by definition of proportion, we have;

By cross multiply we have;

Divide by 3 on both sides we get;

therefore, 40 ounces of cashews will a batch have for every 60 ounces of peanuts.
so you just add 3/8 and 3/4 and the answer is 1.125
