Answer:

D. 18.68

Step-by-step explanation:

$27\div \frac{5}{3}-6+53\times (\frac{2}{5})^2$

Applying PEMDAS as order of operations.

Solving the exponents first $[(\frac{2}{5})^2=\frac{4}{25}]$

$=27\div \frac{5}{3}-6+53\times \frac{4}{25}$

Multiplying $[53\times \frac{4}{25}=8.48]$

$=27\div \frac{5}{3}-6+8.48$

Dividing $[27\div \frac{5}{3}=16.2]$

$=16.2-6+8.48$

Adding and subtracting.

$=18.68$

GREYUIT [131]

Answer: C. She is dividing the entire length into shorter lengths.

The rest of the question would be "How many pieces will she get?"

Step-by-step explanation:

A would be a subtraction problem UNLESS it goes on to ask "how many 1/3 yard pieces can she cut?"

It's a subtraction problem if it's about "how many yards are left?"

B is just backwards and makes no sense with the expression given.
