$p\%=\dfrac{p}{100}\\\\10\%=\dfrac{10}{100}=\dfrac{1}{10}=0.1\\\\10\%\ of\ 26.8\to0.1\cdot26.8=2.68\\\\Answer:\boxed{2.68}$

Other methods:

(1)

$\begin{array}{cccc}100\%&-&26.8&\text{divide by 10}\\10\%&-&2.68\end{array}$

(2)

$\begin{array}{cccc}100\%&-&26.8\\10\%&-&x\end{array}\qquad\text{cross multiply}\\\\100x=(10)(26.8)\\\\100x=268\qquad\text{divide both sides by 100}\\\\x=\dfrac{268}{100}\\\\\boxed{x=2.68}$

1) Shannon and Kristoph are dividing numbers written in scientific notation.

Answer:

The answers will have the same value, beacuse both scientific notations have the same coefficient, 4.2 and 1.4. Also, if you mentally subtract the exponents of those powers, you would have the same exponent. So, equal coefficient and equal exponent will give the same result.

The value of each expression can be found by dividing coefficients and powers.

$\frac{4.2 \times 10^{9} }{1.4 \times 10^{4} }=3 \times 10^{9-4} = 3 \times 10^{5}$
