Question

Помогите решить: (/-это дробь) 31)0,3-(-5/9) 32)-10:4 33)-1/7:(-5) 34)11/3∙13/7 35)4∙61/3∙3/8 36)33/5:27/10

Answer 1

31) 3/10 + 5/9 = 27/90 + 50/90 = 77/90
32) - 2,5
33) -1/7 * (-1/5) = 1/35
34) здесь умножение? 143/21 = 6целых 17/21
35) 61/2 = 30целых 1/2
36) 33/5 * 10/21 = 22/9 = 2 целых 4/9

Answer 2

I can help you with some math problems. Here are the solutions:

1) $0.3-(-\frac{5}{9})=0.3+\frac{5}{9}=\frac{27}{90}+\frac{50}{90}=\frac{77}{90}$ 2) $-10:4=-\frac{10}{4}=-\frac{5}{2}$ 3) $-\frac{1}{7}:(-5)=-\frac{1}{7}\cdot\frac{1}{-5}=\frac{1}{35}$ 4) $\frac{11}{3}\cdot\frac{13}{7}=\frac{143}{21}$ 5) $4\cdot\frac{61}{3}\cdot\frac{3}{8}=4\cdot\frac{61}{8}=\frac{244}{8}=61$ 6) $\frac{33}{5}:\frac{27}{10}=\frac{33}{5}\cdot\frac{10}{27}=\frac{110}{135}=\frac{22}{27}$
