Question

помогите пожалуйста ​

Answer 1

Пошаговое объяснение:

1)

$7\frac{14}{15} + 2 \frac{1}{15} = 9 \frac{15}{15} = 10$

2)

$9 \frac{24}{27} + 12 \frac{13}{27} = 21 \frac{37}{27} = 22 \frac{10}{27}$

3)

$1 - \frac{12}{19} = \frac{19}{19} - \frac{12}{19} = \frac{7}{19}$

4)

$8 - 3 \frac{6}{15} = 7 \frac{15}{15} - 3 \frac{6}{15} = 4 \frac{9}{15} = 4 \frac{3}{5}$

5)

$12 - 11 \frac{6}{11} = 11 \frac{11}{11} - 11 \frac{6}{11} = \frac{5}{11}$

Answer 2

1) 7 14/15+2 1/15= 9 15/15=10

2) 9 24/27+12 13/27= 21 37/27= 22 10/27

3) 1 -12/19=1/1-12/19=19/19-12/19=7/19

4) 8- 3 6/15=8/1-51/15=120/15-51/15=69/15=4 9/15= 4 3/5

5) 12-11 6/11= 12/1-127/11= 132/11-127/11=5/11
