Answer:

Your answer is D. 16 3/4

Step-by-step explanation:

10 1/12 + 6 2/3 = 67

= 16 3/4

= 16.75

Calculation steps

Conversion a mixed number to a improper fraction: 10 1/12 = 10 · 12 + 1/12

= 121/12

Conversion a mixed number to a improper fraction:

6 2/3 = 6 · 3+2/3

= 20/3

Add: 121/12 + 20/3 = 121/12 + 20 · 4/3 · 4 = 121/12 + 80 12 = 121 + 80/12 = 201/12 = 67/4

Weights of different sandwiches in two lengths are shown in the table.

Alexandra [31]

Answer:

Egg salad sandwich is proportional to its length

Step-by-step explanation:

Weight of Sandwiches by Length of Roll

6-inch Roll 12-Inch Roll

Cheese sandwich $\frac{1}{4}$ $\frac{3}{4}$

Chicken salad sandwich $\frac{3}{4}$ $1\frac{3}{4}$

Egg salad sandwich $\frac{2}{3}$ $1\frac{1}{3}$

For cheese sandwich proportion

$\frac{6}{\frac{1}{4}}=\frac{12}{\frac{3}{4}}\\24 \neq 16$

So, Cheese sandwich weight is not proportional to its length

For Chicken salad sandwich proportion

$\frac{6}{\frac{3}{4}}=\frac{12}{\frac{7}{4}}\\8 \neq \frac{48}{7}$

So, chicken salad sandwich is not proportional to its length

For Egg salad sandwich proportion

$\frac{6}{\frac{2}{3}}=\frac{12}{\frac{4}{3}}\\9=9$

So, egg salad sandwich is proportional to its length
