Answer:
7 boxes of pencils and 5 boxes of erasers.
Step-by-step explanation:
The least common denominator of these two numbers are 70. 7×10 and 14×5. So she is purchasing the same quantity of both.
(-2/3)*(-2 1/4)*(3/4) Convert the mixed fraction to improper fraction.
(-2/3)*(-9/4)*(3/4) Then you multiply the numerators with numerators and denominators with denominators
(-2*-9*3) negative times negative is positive, so the negative sign is gone
-------------
(3*4*4*) The lines (-----) is the line of the fraction
54/48 This is the product of this multiplication, now you need to simplify
by reducing the numbers of the fraction
9/8 And that would be the answer
