Question

Complete the following proportion by filling the box. :13::12:52​

Answer 1

Answer:

$x : 13 : : 12 : 52 \\ \frac{x}{13} = \frac{12}{52} \\ 52x = 13 \times 12 \\ 52x = 156 \\ x = \frac{156}{52} \\ \boxed{x = \underline{ \underline{ 3}}} \\ \\ x : 13 : : 12 : 52 \\ \large{3 : 13 : : 12 : 52}$

Answer 2

Step-by-step explanation:

let the unknown number = x

• x : 13 :: 12 : 52
• $\frac{ x }{ 13 } \: {=} \: \frac{ 12 }{ 52 }$
• 52x = 12 × 13
• 52x = 156
• x = $\frac{ 156 }{ 52 }$
• x = 3

:. 3 : 13 :: 12 : 42
