Question

Resuelve la siguiente resta de fracciones:
7/8 - 1/2=? -? =?
9/10 - 1/4 =? -? =?
5/6 - 3/5 =? -? =? ​

Answer 1

7/8-1/2=14/16-8/16=3/8

7/8 - 1/2

7×2 = 14

8x2 = 16

14/16

1x8 = 8

2x8 = 16

8/16

14/16-8/16 = 6/16 = 3/8

9/10-1/4=36/40-10/40=13/20

9/10 - 1/4

9x4=36

10x4=40

36/40

1x10=10

4x10=40

10/40

36/40-10/40 = 26/40 = 13/20

5/6-3/5=25/30-18/30=7/30

5/6 - 3/5

5x5=25

6x5=30

25/30

3x6=18

5x6=30

18/30

25/30-18/30 = 7/30
