Barbara’s orange weighs 5 ounces. She ate 1/3 of the orange. How many ounces of the orange did Barbara eat?
Ede4ka [16]

Answer:

1.67 ounces

Step-by-step explanation:

All you have to do is take 5 and multiply that by 1/3 to get what 1/3 of 5 is. By doing that you get 5/3 which simplifies to 1.6667 repeating but you can round to 1.67 and thats your answer.

? = 12*3/4 = 9 
so if there are 12 boys in the class we will have 9 girls in the class :)))

Simplify the following surd expressions<br> a) 7/3 - 2/3 + V3 - 3V3
Nata [24]

Answer:

\frac{7}{3}-\frac{2}{3}+\sqrt{3}-3\sqrt{3}=\frac{5}{3}-2\sqrt{3}    

Step-by-step explanation:

Given the expression

\frac{7}{3}\:-\:\frac{2}{3}\:+\:v^3\:-\:3v^3

solving the expression

\frac{7}{3}\:-\:\frac{2}{3}\:+\:\sqrt{3}-3\sqrt{3}

combine the fractions i.e \frac{7}{3}-\frac{2}{3}=\frac{5}{3}

\frac{7}{3}\:-\:\frac{2}{3}\:+\:\sqrt{3}-3\sqrt{3}=\frac{5}{3}+\sqrt{3}-3\sqrt{3}

add similar elements  i.e \sqrt{3}-3\sqrt{3}=-2\sqrt{3}

                                 =\frac{5}{3}-2\sqrt{3}      

Thus,

\frac{7}{3}-\frac{2}{3}+\sqrt{3}-3\sqrt{3}=\frac{5}{3}-2\sqrt{3}
