Question

1)9целых 3/7 + 2/7
2)5/22+ 3целых 17/22
3)3целых 3/5+2целых 1/5
4)2цнлых 1/2+3целых 1/2​

Answer 1

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

2) 5/22 + 3 17/22 = 3 (5+17)/22 = 3 22/22 = 4

3) 3 3/5 + 2 1/5 = 3+2 (3+1)/5 = 5 4/5 = 5 8/10 = 5,8

4) 2 1/2 + 3 1/2 = 2+3 (1+1)/2 = 5 2/2 = 6

Answer 2

Пошаговое объяснение:

$\[\begin{gathered}9\frac{3}{7}+\frac{2}{7}=9+\frac{{3+2}}{7}=9+\frac{5}{7}=\boxed{9\frac{5}{7}} \hfill \\\frac{5}{{22}}+3\frac{{17}}{{22}}=3+\frac{5}{{22}}+\frac{{17}}{{22}}=3+\frac{{22}}{{22}}=3+1=\boxed4 \hfill \\ \end{gathered} \]$

$\[\begin{gathered}3\frac{3}{5}+2\frac{1}{5}=3+2+\frac{3}{5}+\frac{1}{5}=5+\frac{{3+1}}{5}=5+\frac{4}{5} = \boxed{5\frac{4}{5}} \hfill \\2\frac{1}{2}+3\frac{1}{2}=2+3+\frac{1}{2}+\frac{1}{2}=5+\frac{{1+1}}{2}=5+\frac{2}{2}=5+1 =\boxed6 \hfill \\ \end{gathered} \]$
