Answer 1

Respuesta:

3/8 + ¼ =

3/8 + 2/8 = 5/8

3/9 + 1/3 =

3/9 + 3/9 = 6/9 ÷2

1.5 +3.2 = 4.7

10 – 2.5 = 7.5

5.4 + 2.7 =8.1

3.9 + 1.1 =5

½ - ¼ =

2/4 - 1/4 = 3/4

¼ + ¼ + ½ =

1/4 + 1/4 + 2/4 = 4/4 => 1

¾ - ½ =

3/4 - 2/4 = 1/4

9/10 – 2/5 =

9/10 - 4/10 = 5/10 ÷ 5 => 1/2

8/12 + 1/6 =

8/12 + 2/12 = 10/12 ÷ 2 => 5/6

4/12 + 1/6 =

4/12 + 2/12 = 8/12 ÷ 4 => 2/3

20 – 7.7 = 12.3

15.4 + 5.4 = 20.8
