Question

3 ( целые )1/16:(х-5/16)=7/8
Помогите пожалуйста!!!

Answer 1

$x - \frac{5}{16} = 3 \frac{1}{16} \div \frac{7}{8} = \\ \frac{49}{16} \times \frac{8}{7} = \frac{7}{2} = 3 \frac{1}{2}$
$x = 3 \frac{1}{2} + \frac{5}{16} = \\ 3 \frac{8}{16} + \frac{5}{16} = 3 \frac{13}{16}$

Answer 2

7/8:3целых1/16=x-5/16

14/16:47/16+5/16=x

14/47+5/16=x

224/752+235/752=x

X=459/752
