Question

x-три целых пять шестых= пять целых четыре девятых прошу помогите!

Answer 1

3 5/8 + 1 2/3 = 3 15/24 + 1 16/24 = 4 31/24 = 5 7/24 
=======================================
4 4/9 - 2 5/6 = 4 8/18 - 2 15/18 = 3 26/18 - 2 15/18 = 1 11/18 
========================================
6 7/12 + ( 5 3/40 - 4 8/15 ) = 6 70/120 + 5 9/120 - 4 64/120 = 11 79/120 - 4 64/120 =
= 7 15/120 = 7 1/8 

Answer 2

$x- 3\frac{5}{6}=5 \frac{4}{9} \\x=5 \frac{4}{9}+3 \frac{5}{6} \\x=5 \frac{8}{18}+3 \frac{15}{18} \\x=8 \frac{23}{18} \\x=9 \frac{5}{18}$
