Question

. Realiza las siguientes operaciones 6 1/15-4 1/30+7/25; 3/4*4/5*5/6; 1 1/2+2 1/3; (5/6+3 1/4)+12/3

Answer 1

Explicación paso a paso:

✔6 1/15 - 4 1/30 + 7/25

pasar a fraccion impropia:

6 1/15 = 91/15

4 1/30 = 121/30

por lo tanto:

91/15 - 121/30 + 7/25

MCM(15, 30, 25= = 150

910/150 - 605/150 + 42/150

= 347/150

✔3/4 * 4/5 * 5/6

3 * 4 * 5/4 * 5 * 6

60/120 = 1/2

✔1 1/2 + 2 1/3

a fracciòn impropia:

1 1/2 = 3/2

2 1/3 = 7/3

por lo tanto:

3/2 + 7/3

MCM(2, 3) = 6

9/6 + 14/6

= 23/6 = 3 5/3

✔(5/6 + 3 1/4) + 12/3

5/6 + 3 + 1/4 + 4

5/6 + 1/4 + 7

MCM(6, 4) = 12

7 + 10/12 + 3/12

7 + 13/12

7 13/12 = 97/12

espero q te ayude :D
