Question

помогите плиз решить​

Answer 1

1)$\frac{7}{8}$-(-$\frac{3}{10}$)=$\frac{70}{80}$+$\frac{24}{80}$=$\frac{94}{80}$=1$\frac{7}{40}$

2)11/12-17/18=33/36-34/36=-1/36

3)-3/7-9/14=-6/14-9/14=-1$\frac{1}{14}$

4)-5/9-(-3/4)= -20/36-27/36=-47/36=-1$\frac{13}{36}$

5)3$\frac{11}{12}$-(-4$\frac{4}{9}$)=1$\frac{17}{36}$

6)-4$\frac{5}{17}$-6=-1$\frac{12}{17}$

7)1.375-3.250=-1.875=-1$\frac{7}{8}$

8)-2$\frac{14}{15}$-1$\frac{19}{45}$=-3$\frac{42+19}{45}$=-4$\frac{16}{45}$

9)-3$\frac{1}{6}$-(-1$\frac{1}{4}$)=-1$\frac{22}{24}$=-1$\frac{11}{12}$
