Decompose Fractions Multiple Ways Practice Test

Emma wrote three different decompositions for $$\frac{8}{10}$$: Decomposition 1: $$\frac{8}{10} = \frac{5}{10} + \frac{3}{10}$$ Decomposition 2: $$\frac{8}{10} = \frac{4}{10} + \frac{4}{10}$$ Decomposition 3: $$\frac{8}{10} = \frac{2}{10} + \frac{2}{10} + \frac{4}{10}$$ Which statement about her decompositions is true?

Look at the equation: $$\frac{9}{14} = \frac{a}{14} + \frac{b}{14} + \frac{c}{14}$$ where $$a$$, $$b$$, and $$c$$ are different positive whole numbers. Which set of values for $$a$$, $$b$$, and $$c$$ makes this equation true?
