The equation given is \( \frac{2}{9} = \frac{14}{?} \). To solve for the missing number, cross-multiply:
\[ 2 \times ? = 9 \times 14 \]
Calculate \( 9 \times 14 = 126 \), so:
\[ 2 \times ? = 126 \implies ? = \frac{126}{2} = 63 \].

Verification: Substituting 63 into \( \frac{14}{63} \) simplifies to \( \frac{2}{9} \), confirming correctness. Other options (14, 16, 15) do not satisfy the equation.

GPT-4o To find the number that makes the statement true, we need to solve the proportion:

\[ \frac{2}{9} = \frac{14}{?} \]

Let's denote the unknown number by \( x \). The statement can be written as:

\[ \frac{2}{9} = \frac{14}{x} \]

To find \( x \), we can cross-multiply:

\[ 2 \cdot x = 9 \cdot 14 \]

Solving for \( x \):

\[ 2x = 126 \]
\[ x = \frac{126}{2} \]
\[ x = 63 \]

So the number that makes the statement true is 63.

To find the number that makes the statement true, we need to find the value of x that makes the equation:

2/9 = 14/x

We can cross-multiply to get:

2x = 14 × 9

2x = 126

x = 126/2

x = 63

So, the correct answer is:

2/9 = 14/x, cross multiply gives 2x = 14×9 = 126, x = 126÷2 = 63.

minimax To solve the proportion 2/9 = 14/x, we can cross-multiply to find the value of x:

2 * x = 9 * 14

Now, solve for x:

x = (9 * 14) / 2
x = 126 / 2
x = 63

So the correct answer is:

D. 63

kimi To solve this problem, we need to find the number that makes the fraction \( \frac{2}{9} \) equal to \( \frac{14}{x} \). We can set up the equation as follows:

\[ \frac{2}{9} = \frac{14}{x} \]

To find \( x \), we cross-multiply:

\[ 2 \cdot x = 9 \cdot 14 \]

\[ 2x = 126 \]

Now, divide both sides by 2 to solve for \( x \):

\[ x = \frac{126}{2} \]

\[ x = 63 \]

So the correct answer is:

Explanation: This is a problem involving fractions. The statement is saying that 2/9 is equal to 14 over some unknown number. To solve this, set up the fractions equal to each other: 2/9 = 14/x where x is the unknown number. Then, cross multiply to get: 2x = 126. Divide both sides by 2 to solve for x: x = 63.

zhipu To find the number that makes the statement \( \frac{2}{9} = \frac{14}{?} \) true, we can set up a proportion and solve for the unknown.

Given:
\[ \frac{2}{9} = \frac{14}{x} \]

Cross-multiply to solve for \( x \):
\[ 2x = 9 \times 14 \]
\[ 2x = 126 \]

Divide both sides by 2:
\[ x = \frac{126}{2} \]
\[ x = 63 \]

Therefore, the number that makes the statement true is 63.

deepseekv3 To solve the equation:

\[
\frac{2}{9} = \frac{14}{?}
\]

Let the unknown number be \( x \). Then:

\[
\frac{2}{9} = \frac{14}{x}
\]

Cross-multiply to solve for \( x \):

\[
2x = 14 \times 9
\]

\[
2x = 126
\]

\[
x = \frac{126}{2} = 63
\]

Thus, the correct answer is:
