Answer 1

25 1/4:(5 1/2-3,5)-16 1/3:7=10 7/24
1)5 1/2-3,5=11/2-35/10=55/10-35/10=20/10
2)25 1/4:20/10=101/4×10/20=101×1 и 4×2=101/8
3)16 1/3:7=49/3:7/1=49/3×1/7=7×1 и 3×1=7/3
4)101/8-7/3=303/24-56/24=247/24=10 7/24

Готово❤️

Answer 2

Ответ:

$25\frac{1}{4} : (5\frac{1}{2} -3,5)-16\frac{1}{3} :7 = 6\frac{1}{8}$

Пошаговое объяснение:

$\\ 3,5=3\frac{1}{2}\\ 5\frac{1}{2} -3,5=5\frac{1}{2}-3\frac{1}{2}=2\\ \\ 25\frac{1}{4} :2=25\frac{1}{4} *\frac{1}{2} =\frac{25*4+1}{4} *\frac{1}{2} =\frac{101}{4} *\frac{1}{2} =\frac{101*1}{4*2} =\frac{101}{8} \\ \\ 16\frac{1}{3} :7=\frac{16*3+1}{3} *\frac{1}{7} =\frac{49}{3} *\frac{1}{7} =\frac{49*1}{3*7}=\frac{49}{21}$

$\\ \frac{101}{8} -\frac{49}{21}=\frac{101*21}{8*21} -\frac{49*8}{21*8} =\frac{2121}{168} -\frac{329}{168} =\frac{2121-329}{168} =\frac{1729}{168}=10\frac{49}{168}=6\frac{7}{24}$
