4/5 x+9/10 =5 1/5

解答

\frac{4}{5} x + \frac{9}{10} = 5 \frac{1}{5}

解答

x = 5 \frac{3}{8}

+1

十进制

x = 5.375

求解步骤

\frac{4}{5} x + \frac{9}{10} = 5 \frac{1}{5}

将带分数转换为假分式:

5 \frac{1}{5} = \frac{26}{5}

\frac{4}{5} x + \frac{9}{10} = \frac{26}{5}

将

\frac{9}{10}

到右边

\frac{4}{5} x = \frac{43}{10}

在两边乘以

5

4 x = \frac{43}{2}

两边除以

4

x = \frac{43}{8}

将假分式转换为带分数:

\frac{43}{8} = 5 \frac{3}{8}

x = 5 \frac{3}{8}

流行的例子

\frac{1}{2} x = 10

solvefor x, 1/5 x+4y= 32/8

so l v e f or x, \frac{1}{5} x + 4 y = \frac{32}{8}

3/2+3/4 a= 1/4 a-1/2

\frac{3}{2} + \frac{3}{4} a = \frac{1}{4} a - \frac{1}{2}

-1/5-5/3 m= 3/5

- \frac{1}{5} - \frac{5}{3} m = \frac{3}{5}

solvefor x,5x+10=10y

so l v e f or x, 5 x + 10 = 10 y
