To solve the inequality \( \frac{60}{g} > 3 \times 5 \), we first simplify the right side:
\[ 3 \times 5 = 15 \] So, we are solving:
\[ \frac{60}{g} > 15 \]
Next, we multiply both sides by \( g \) (assuming \( g > 0 \) to avoid division by zero and to keep the inequality direction unchanged):
\[ 60 > 15g \]
Now, divide both sides by 15:
\[ \frac{60}{15} > g \]
This simplifies to:
\[ 4 > g \quad \text{or} \quad g < 4 \]
Now we check the provided sets of numbers to see which values are less than 4:
- Set \( {4, 5, 6} \): Contains 4, which does not satisfy \( g < 4 \) (excluded).
- Set \( {2, 3, 4} \): Contains 4, which does not satisfy \( g < 4 \) (excluded).
- Set \( {1, 2, 3} \): All numbers (1, 2, 3) satisfy \( g < 4 \) (included).
- Set \( {3, 4, 5} \): Contains 4, which does not satisfy \( g < 4 \) (excluded).
Therefore, the only set of numbers where all the number solutions satisfy \( g < 4 \) is:
\({1, 2, 3}\)
