Question

1.2 3/5+3 1/2-4 5/6=
2.2 1/3+5/6=
3.2/3+1/5-1/2=
Tolong dengan caranya?

Answer 1

Caranya Samakan Bentuk Penyebutnya.

1. 2 3/5 + 3 1/2 - 4 5/6
= 13/5 + 7/2 - 29/6
=  78/30 + 105/30 - 145/30
= 38/30 
= 19/15
= 1 4/15

2. 2 1/3 + 5/6
= 7/3 + 5/6
= 42/18 + 15/18
= 57/18
= 19/6
= 3 1/6

3. 2/3 + 1/5 - 1/2
= 20/30 + 6/30 - 15/30
= 11/30

Answer 2

1. 2 3/5+3 1/2-4 5/6 =13/5+7/2-29/6
                             = 78/30+105/30-145/30
                             = 38/30 = 19/15 = 1 4/15
2. 2 1/3+5/6 = 7/3+5/6
                  = 14/6+5/6
                 = 19/6 = 3 1/6
3. 2/3+1/5-1/2 = 20/30+6/30-15/30
                    = 11/30
