Answer:
D. ) 10 1/2 pounds
Step-by-step explanation:
Total weight
a science teacher has 4 [tex]\frac{2}{3}[/tex] packages of bird seed. and each package weighs
2[tex]\frac{1}{4}[/tex] pounds.
in order to find the amount of pounds of bird seed the teacher has'
the formula that can be used is :
number of packages * weight per package
= 4 [tex]\frac{2}{3}[/tex] * 2[tex]\frac{1}{4}[/tex]
we can first convert to a mixed fraction which is :
= [tex]\frac{14}{3} * \frac{9}{4}[/tex]
= [tex]\frac{14*9}{3*4}[/tex]
= [tex]\frac{126}{12} \\[/tex]
simplify
= 10 1/2 pounds
hence answer is D.) 10 1/2 pounds
