tolong dijawab ya...

2/3+4/5=(disamakan penyebutnya)
10+12/15=
22/15=1 7/15

2/3+1/2=
7/6=1 1/6

2 1/2+3 1/4=
5/2+13/4=
23/4=
5 3/4

1.
*[tex] \frac{2}{3} + \frac{4}{5} = \frac{10}{15} + \frac{12}{15} = \frac{22}{15} [/tex][tex]1 \frac{7}{15} [/tex]
*[tex] \frac{2}{3} + \frac{1}{2} = \frac{4}{6} + \frac{3}{6} = \frac{7}{6} =1 \frac{1}{6} [/tex]
2.
[tex]2 \frac{1}{2} + 3 \frac{1}{4} = \frac{5}{2} + \frac{13}{4} [/tex]
[tex] \frac{10}{4} + \frac{13}{4} = \frac{23}{4} =5 \frac{3}{4} [/tex]
