Answer 2

Answer:

(7/16)+(-1/12)+(-5/4)= (21+(-4)+(-60))/48

=(21-4-60)/48 = -43/48

Step-by-step explanation:

1)

First open the brackets and multiply the sign

(7/16)+(-1/12)+(-5/4)

= (7/16)-(1/12)-(5/4)

2)

Take the LCM of the denominators

LCM of 16,12 and 4 =48

7/16=21/48

1/12=4/48

5/4=60/48

3)

Take the denominator common

(7/16)-(1/12)-(5/4)

= (21/48)-(4/48)-( 60/48)

= (21-4-60)/48

= -43/48
