Answer:

30% of 280 is 84.

I checked it with a calculator and got the same result being 84.

Round each fraction to the nearest half and find the estimate.

erastova [34]

Answer: The result is one half ( $\frac{1}{2}$ )

Step-by-step explanation:

We have the following expression:

$\frac{2}{6}+\frac{1}{6}$

Since both fractions have the same denominator, we can just add both numerators and keep the denominator:

$\frac{2+1}{6}=\frac{3}{6}$

Dividing numerator and denominator by $3$ :

$\frac{\frac{3}{3}}{\frac{6}{3}}=\frac{1}{2}$ This is the result
