Tamika has two bags of trail mix. Each has a combination of 60 pieces of fruit and nuts.

Ratio of fruit to nuts in the first bag:3
5

Ratio of fruit to nuts in the second bag:7
10

Which bag has more fruit? Use the ratios to justify your answer.
The first bag, because the ratio is greater.
The first bag, because the ratio is smaller.
The second bag, because the ratio is greater.
The second bag, because the ratio is smaller

1 answer

To compare the amount of fruit in each bag, let's first analyze the ratios and calculate the quantities of fruit and nuts based on the specified ratios for both bags.

First Bag:

  • Ratio of fruit to nuts: 3:5
  • Total pieces: 60

Let the amount of fruit be \(3x\) and the amount of nuts be \(5x\). Therefore, we can set up the equation: \[ 3x + 5x = 60 \] \[ 8x = 60 \] \[ x = 7.5 \]

Now calculating the amounts:

  • Fruit: \(3x = 3 \times 7.5 = 22.5\)
  • Nuts: \(5x = 5 \times 7.5 = 37.5\)

Second Bag:

  • Ratio of fruit to nuts: 7:10
  • Total pieces: 60

Let the amount of fruit be \(7y\) and the amount of nuts be \(10y\). Therefore, we can set up the equation: \[ 7y + 10y = 60 \] \[ 17y = 60 \] \[ y \approx 3.5294 \]

Now calculating the amounts:

  • Fruit: \(7y = 7 \times 3.5294 \approx 24.69\)
  • Nuts: \(10y = 10 \times 3.5294 \approx 35.29\)

Comparison:

  • First Bag: \(22.5\) pieces of fruit
  • Second Bag: \(24.69\) pieces of fruit

Conclusion:

The second bag has more fruit than the first bag.

Thus, the correct answer is: The second bag, because the ratio is greater.
