解

T h e s u m o f tw o co n sec u t i v e n u mb ers i s 54, w ha t a re t h e n u mb ers

The numbers : 26 \frac{1}{2}, 27 \frac{1}{2}

解答ステップ

Represent the numbers with

x

First number : x

Consecutive number : x + 1

A.T.Q.:

x + x + 1 = 54

解く

x + x + 1 = 54 : x = \frac{53}{2}

x + 1 = \frac{53}{2} + 1 = \frac{55}{2}

仮分数を帯分数に変換する:

\frac{53}{2} = 26 \frac{1}{2}

仮分数を帯分数に変換する:

\frac{55}{2} = 27 \frac{1}{2}

The numbers : 26 \frac{1}{2}, 27 \frac{1}{2}
