2 what is the value of the expression below?
\\(\

$$\begin{array}{r}3\\frac{1}{4}\\\\ -1\\frac{7}{8}\\\\ \\hline \\end{array}$$

\\)
a \\(1\frac{1}{4}\\)
b \\(1\frac{3}{8}\\)
c \\(2\frac{3}{8}\\)
d \\(3\frac{1}{2}\\)

Explanation:

Step1: Calculate base recipe total

$1.25 + 2.5 + 1 = 4.75$

Step2: Scale to 3x the recipe

$4.75 \times 3 = 14.25$

Step3: Convert mixed numbers to improper fractions

$3\frac{1}{4} = \frac{13}{4}$, $1\frac{7}{8} = \frac{15}{8}$

Step4: Find common denominator and subtract

$\frac{13}{4} = \frac{26}{8}$, $\frac{26}{8} - \frac{15}{8} = \frac{11}{8} = 1\frac{3}{8}$

Answer:

1. D 14.25
2. B $1\frac{3}{8}$
