Question

$(3 \frac{1}{2} \div 4 \frac{2}{3} + x - 3 \frac{1}{2} ) \times 4 \frac{4}{5} = 10$
​

Answer 1

Ответ: x=29/6=4⁵/₆.

Объяснение:

1. 3¹/₂:4²/₃=(7/2):(14/3)=7*3/(2*14)=3/4.

2. (3/4)-3¹/₂=(3/4)-(7/2)=(3-7*2)/4=(3-14)/4=-11/4

3. 10:4⁴/₅=10:(24/5)=10*5/24=50/24=25/12.

4. x-(11/4)=25/12

x=25/12+11/4=(25+11*3)/12=(25+33)/12=58/12=29/6=4⁵/₆.
