Respuesta: a)11 / 12 - 1 / 3 = 11/12 - 4/12 = 7/12
b)7/8 - 1/4 = 7/8 - 2/8 = 5/8
c)17/18 - 1/3 = 17/18 - 6/18 = 11/18
d)7/18 - 1/3 = 7/18 - 6/18 = 1/18
e)17/24 - 3/8 = 17/24 - 9/24 = 8/24 = 1/3
f)7/15 - 2/5 = 7/15 - 6/15 = 1/15
Explicación paso a paso:
*Como 1/3 = 4/12, entonces 11 / 12 - 1 / 3 = 11/12 - 4/12 = 7/12
** Como 1/4 = 2/8, entonces 7/8 - 1/4 = 7/8 - 2/8 = 5/8
*** Como 1/3 = 6/18, entonces 17/18 - 1/3 = 17/18 - 6/18 = 11/18
****Como 1/3 = 6/18, entonces 7/18 - 1/3 = 7/18 - 6/18 = 1/18
***** Como 3/8 = 9/24, entonces 17/24 - 3/8 = 17/24 - 9/24 = 8/24 = 1/3
******Como 2/5 = 6/15, entonces 7/15 - 2/5 = 7/15 - 6/15 = 1/15
Respuesta:
a) 11/12 - 1/3 = 33-12/36 = 21/36 = 8/12 = 2/3
b) 7/8 - 1/4 = 28-8/32 = 20/32 = 10/16 = 5/8
c) 17/18 - 1/3 = 51-18/54 = 33/54
d) 7/18 - 1/3 = 21-18/54 = 3/54
e) 17/24 - 3/8 = 136-72/192 = 64/192
f) 7/15 - 2/5 = 35-30/75 = 5/75 = 1/15
