Question

1)1 3/4+(-1/2)
2)5 2/9+(-1/3)
3) 4 3/8+(-1/4)
4)5 1/2+(-8 5/6)​

Answer 1

Ответ:

1 3/4 + ( - 1 / 2 )=1 3/4-2/4=1 1/4

5 2/9+(-1/3)=5 2/9-3/9=5-1/9=4 8/9

4 3/8+(-1/4)=4 3/8-2/8=4 1/8

5 1/2+(-8 5/6)= 5 3/6-8 5/6=-3 2/6=-3 1/3

4 1/3+(-7 5/9)=4 3/9-7 5/9=-3 2/9

Answer 2

Ответ:

$1)1 \frac{3}{4} + ( - \frac{1}{2} ) = \frac{7}{4} - \frac{1}{2} = \frac{5}{4} = 1 \frac{1}{4} \\ 2)5 \frac{2}{9} + ( - \frac{1}{3} ) = \frac{47}{9} - \frac{1}{3} = \frac{44}{9} = 4 \frac{8}{9} \\ 3)4 \frac{3}{8} - + ( - \frac{1}{4} ) = \frac{35}{8} - \frac{1}{4} = \frac{33}{8} = 4\frac{1}{8} \\ 4)5 \frac{1}{2} + ( - 8 \frac{5}{6} )= \frac{11}{2} - \frac{53}{6} = - \frac{10}{3} = - 3 \frac{1}{3}$
