Question

2 2/7 - 1 1/3

Answer 1

\[2\frac{ 2}{ 7} - 1 \frac{ 1 }{ 3 }\]

Answer 2

\(\color{#00ff00}{2 \dfrac{2}{7} - 1 \dfrac{1}{3}}\)

You have to find the common denominator, in this case it's 21.

\(\color{#00ff00}{2 \dfrac{2}{7} - 1 \dfrac{1}{3}}\)

\(\color{#00ff00}{2 \dfrac{6}{21} - 1 \dfrac{7}{21}}\)

Now subtract the whole numbers and the numerators:

\(\color{#00ff00}{2 \dfrac{6}{21} - 1 \dfrac{7}{21} \rightarrow 1 \dfrac{6-7}{21}}\)

Can you subtract 6 - 7? @jpierson

Answer 3

Then the answer would be \[\frac{ 20 }{ 21 }\] Do you understand what@iGreen and I are explaining?
