Answer 1

Respuesta:

1) 1/5 x 10 + 3/2 x 7 - 5/4 = 465/20

1/5 x 10 = 1/5 x 10/1 = 10/5

10/1

10/5 + 3/2 = 20/10 + 15/10 = 35/10

5 x 2 = 10

2 x 5 = 10

10/5 x 2 = 20/10

3/2 x 5 = 15/10

35/10 x 7 = 35/10 x 7/1 = 245/10

7/1

245/10 - 5/4 = 490/20 - 25/20 = 465/20

10 x 2 = 20

4 x 5 = 20

245/10 x 2 = 490/20

5/4 x 5 = 25/20

2) 6/5 : 3 + 3 x 1/4 - 1/10 = 45/60

6/5 : 3 = 6/5 : 3/1 = 6/15

3/1

6/15 + 3 = 6/15 + 45/15 = 51/15

3/1

1 x 15 = 15

3/1 x 15 = 45/15

51/15 x 1/4 = 51/60

51/60 - 1/10 = 51/60 - 6/60 = 45/60

10 x 6 = 60

1/10 x 6 = 6/60
