The numbers : 38 \frac{1}{3}, 1 \frac{2}{3}

解答ステップ

Represent the numbers with

x and y

number 1 : x

number 2 : y

A.T.Q.:

x = 23 y

x + y = 40

x = 23 y, x + y = 40 : x = \frac{115}{3}, y = \frac{5}{3}

仮分数を帯分数に変換する:

\frac{115}{3} = 38 \frac{1}{3}

仮分数を帯分数に変換する:

\frac{5}{3} = 1 \frac{2}{3}

The numbers : 38 \frac{1}{3}, 1 \frac{2}{3}
