Understanding the Problem

When a customer requests to enlarge a photo to a specific height, it's essential to understand the mathematical concept behind the enlargement. In this scenario, the customer wants the photo to be enlarged to ${$ \frac{23}{4}$}$ its current height. The photo's current height is ${$ \frac{31}{4}$}$ inches. To determine the new height, we need to calculate the enlarged height based on the given ratio.

Calculating the Enlarged Height

To find the enlarged height, we need to multiply the current height by the ratio given by the customer. The ratio is ${$ \frac{23}{4}$}$, which means the new height will be ${$ \frac{23}{4}$}$ times the current height.

Step 1: Convert the Current Height to a Decimal

First, let's convert the current height from a fraction to a decimal. The current height is ${$ \frac{31}{4}$}$ inches, which is equivalent to 7.75 inches.

Step 2: Multiply the Current Height by the Ratio

Now, let's multiply the current height by the ratio. The ratio is ${$ \frac{23}{4}$}$, which is equivalent to 5.75. Multiply the current height (7.75 inches) by the ratio (5.75):

7.75 x 5.75 = 44.5625

Step 3: Convert the Result to a Mixed Number

The result (44.5625) can be converted to a mixed number. To do this, we need to divide the decimal part (0.5625) by the denominator (4):

0.5625 ÷ 4 = 0.140625

Since 0.140625 is equivalent to ${$ \frac{3}{16}$}$, we can rewrite the result as a mixed number:

44.5625 = 44 ${$ \frac{3}{16}$}$

Conclusion

Based on the customer's request, the enlarged height of the photo should be ${ $6 \frac{3}{16}\$}$ inches.

Answer

The correct answer is:

B. ${ $6 \frac{3}{16}\$}$
