Help, quickly if possible.

Answer:
B. 7
Step-by-step explanation:
According to the word problem, Muna is dividing a piece of string that 42 2/3 long into 2/3 pieces.
[tex]\frac{14}{3} /\frac{2}{3}[/tex] (changed to an improper fraction)
Whenever dividing fractions, remember this:
SAME, CHANGE, RECIPROCAL (FLIP)
KEEP THE FIRST FRACTION THE SAME
CHANGE THE DIVISION SIGN TO A MULTIPLICATION SIGN
FLIP THE SECOND FRACTION
[tex]\frac{14}{3} *\frac{3}{2} =\frac{42}{6}[/tex]
[tex]\frac{42}{6} =7[/tex]
I, therefore, believe Muna will have 7 pieces of string.
