Step-by-step explanation:

This is done just by opening the brackets and afterwards using bodmas or pemdas.

6(2 +v) - 4(2v +1 )

we start with paranthesis or brackets first.

12 + 6v - 8v - 4

A survey by the state health department found that the average person ate 208 pounds of vegetables last year and 125 5/8 pounds

jonny [76]

Answer: The fraction of pounds of fruits over total pounds of fruits and vegetables is given by

$\frac{25125}{66724}$

Step-by-step explanation:

Since we have given that

Total amount of vegetables = 208 pounds

Total amount of fruits is given by

$125\frac{5}{8}\text{ pounds}$

Total amount of fruits and vegetables is given by

$208+125\frac{5}{8}\\\\=208+\frac{1005}{8}\\\\=\frac{1664+1005}{8}\\\\=\frac{2669}{8}\\\\=333.625\text{ pounds }$

So, we need to find the fraction of pounds of fruits over the total pounds of fruit and vegetables :

$\frac{\text{Pounds of fruits }}{\text{ total pounds of fruits and vegetables}}\\\\=\frac{\frac{1005}{8}}{333.62}\\\\=\frac{1005}{8\times 333.62}\\\\=\frac{1005}{2668.96}=\frac{25125}{66724}$
