Answer:
B. 7
Explanation:
According to the word problem, Muna is dividing a piece of string that 42 2/3 long into 2/3 pieces.
(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
I, therefore, believe Muna will have 7 pieces of string.
