Question

fracciones 7/12+ 1/4+3/8​

Answer 1

Respuesta:

29 / 24

Explicación paso a paso:

7 / 12 + 1 / 4 + 3 / 8

= (7 × 4 + 12 × 1) / (12 × 4) + 3 / 8

= (28 + 12) / 48 + 3 / 8

= 40 / 48 + 3 / 8

= 20 / 24 + 3 / 8

= 10 / 12 + 3 / 8

= 5 / 6 + 3 / 8

= (5 × 8 + 6 × 3) / (6 × 8)

= (40 + 18) / 48

= 58 / 48

= 29 / 24
