Gambar Jawaban

Jawaban:

a. (-¾ + ⅓) + ⅚

= (-9/12 + 4/12) + ⅚

= (-5/12) + ⅚

= – 5/12 + 10/12

= 5/12

b. (-⅔) + (½ + ¾)

= (-⅔) + (2/4 + ¾)

= (-⅔) + 5/4

= -8/12 + 15/12

= 7/12

c. 5/3 + (⅙ + ½)

= 5/3 + (⅙ + 3/6)

= 5/3 + (4/6)

= 5/3 + ⅔

= 7/3

= 2 ⅓

d. (2/7 + ½) + (-¾)

= (4/14 + 7/14) + (-¾)

= 11/14 + (-¾)

= 22/28 + (-21/28)

= 22/28 – 21/28

= 1/28
