Question

Michelle is having a poster printed from a picture that is 4 inches wide by 6 inches tall. The enlarged poster is 20 inches wide and 30 inches tall. Which proportion can be used to represent the picture sizes?
StartFraction 6 over 4 EndFraction = StartFraction 20 over 30 EndFraction
StartFraction 4 over 6 EndFraction = StartFraction 20 over 30 EndFraction
StartFraction 4 over 6 EndFraction = StartFraction 30 over 20 EndFraction
StartFraction 4 over 30 EndFraction = StartFraction 6 over 20 EndFraction

Answer 1

Answer:

B

Step-by-step explanation:

This is becuase 30 and 6 are both the inches in height so their units must line up same goes with 4 and 20 becuase they are the same unit they must line up accordingly in the equation.

Answer 2

Answer:

The correct answer is:

Option 2: $\frac{4}{6} = \frac{20}{30}$

Step-by-step explanation:

Given that

Width of picture = 4 inches

Length of picture = 6 inches

Now

Width of poster = 20 inches

Length of poster = 30 inches

The proportion of the picture will be:

$\frac{width}{length} = \frac{4}{6}$

Similarly the proportion of poster can be written as:

$\frac{width}{length} = \frac{20}{30}$

Both proportions when combined can be written as:

$\frac{4}{6} = \frac{20}{30}$

Hence,

The correct answer is:

Option 2: $\frac{4}{6} = \frac{20}{30}$
