Question

Simplify.
(i) -3/10 + 12 / -10 + 14/ 10
(ii) -5/10+ 6/13+8
(iii) -5/10+9/7+3/20+-11/14
(iv) 5/36+-7/8+6/-72+ -3/-12​
​

Answer 1

Step-by-step explanation:

(I). -3/10+12/-10+14/10

-3-12+14/10

-1/10

(II) -5/10+6/13+8

-65+60+1040/130

-5/1040/130

1035/130

57/26

(III). -5/10+9/7+3/20+-11/14

first take LCM of 10,7,20and 14

-70+180+21-110/140

-180+201/140

21/140

3/20

similarly in (IV) part first take LCM then solve it.

and there is +-7/8 which means -7/8 because (+)(-)

will always be (-) same as -3/-12 so it will be 3/12 because (-) will be canceled.

hope this will help you......
