솔루션 단계

Represent the numbers with

x

First number : x

Consecutive number : x + 2

A.T.Q.:

x + 5 (x + 2) = 29

x + 5 (x + 2) = 29

해결 :

x = \frac{19}{6}

x + 2 = \frac{19}{6} + 2 = \frac{31}{6}

부적절한 분수를 혼합 숫자로 변환:

\frac{19}{6} = 3 \frac{1}{6}

부적절한 분수를 혼합 숫자로 변환:

\frac{31}{6} = 5 \frac{1}{6}

Select the smallest solution:

3 \frac{1}{6}

The smallest number : 3 \frac{1}{6}
