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
