* 2 2/5 + 1 1/3 = * 1 1/2 + 2/3 + 3/4 = * 3 2 /6 + 4 3/9 = * 7 - 3/4 = * 5 - 2/4 = mohon dengan cara ya kak...tolong di bantu

1. 2 2/5= 12/5
1 1/3 = 4/3
= 12/5 + 4/3 = 36/15 + 20/15
= 56/15 = 3 11/15
2. 1 1/2 + 2/3 + 3/4
= 3/2 + 2/3 +3/4 = 18 /12 + 8/12 +9/12
= 35/12 = 2 11/12.
3. 3 2/6 + 4 3/9
= 20/6 + 39/9 = 60/18 +78/18 = 138/18
= 7 12/18 = 7 2/3
4. 7 - 3/4 = 7/4 -3/4 = 4/4 = 1
5.5 -2/4 = 5/4-2/4 = 3/4

smoga bermanfaat jikaa ada yg salah smoga bisa dimaafkan wassalam mualaikum jika engkau islam . selamat malam jika kalian beragama lain

[tex]2 \times \frac{2}{5} \\ = \frac{5 \times 2 + 2}{5} \\ = \frac{12}{5} \\ \frac{12}{5} + \frac{11}{3} \\ = \frac{36}{15} + \frac{55}{15} \\ = \frac{91}{15} \\ = 6 \times \frac{1}{15} [/tex]
*11/2+2/3+3/4=(sama dengan cara yang diatas

=66/12+8/12+9/12
=83/12
=6 11/12

*3 2/6+4 3/9
=20/6+39/9
=60/18+78/18
=138/18
=7 12/18
=7 2/3

*7-3/4=
semua ruas kali 4------>(sesuai dengan penyebutnya)
28-3=25
(semua ruas bagi 4)
=25/4
=6 1/4

*5-2/4=
semua ruas kali 4
20-2=18
(semua ruas bagi 4)
=18/4
=4 2/4
=4 1/2

mohon maaf bila ada kesalahan ;)
