Tolong ya Kakak butuh buat besok

1.69/8+7/2=69/8+28/8=97/8
=97/8=12 1/8(B)
Maaf saya cuma bisa yang nomer satu!

1.)8 5/8+3 1/2
=69/8+7/2
=69/8+28/8
=97/8
=12 1/8 (B)

2.)1 5/6+3 2/8+ 1 1/3
=11/6+26/8+4/3
=44/24+78/24+32/24
=154/24
=6 10/24
=6 5/12(C)

3.)3 2/3-3/4-1 1/2
=11/3-3/4-3/2
=44/12-9/12-18/12
=17/12
=1 5/12(A)

4.)7 3/4+1 7/8-3 5/8
=31/4+15/8-29/8
=62/8+15/8-29/8
=48/8
=6(D)

5.)3,35+2 1/4-0,8
=3,35+2,25-0,8
=5,6-0,8
=4,8(B)

6.)7,76-(3,195+2,82)
=7,76-6,015
=1,745(B)

semoga membantu
