Question

Di bantu ya pakai cara thx

Answer 1

A. (2 1/9 + 4 2/9) - 3 5/9
= 2+4 (1/9 + 2/9) - 3 5/9
= 6 3/9 - 3 5/9
= (6-3) 3/9 - 5/9
= 2 7/9 itu jwbanny

b. - 1 2/3 - (-4 3/5)
(-1-(-4)) 2/3 - 3/5
= 3 2/3 - 3/5
= (3) 10/15 - 9/15
= (3) 10/15 - 9/15
= 3 1/15 itu jawaban

c. (1/4 + 1/2) - 5/6
= (1/4 + 2/4) - 5/6
= 3/4 - 5/6
= 9/12 - 10/12
= - 1/12
d. 3 1/5 × 3/4 × (-2 2/3)
= 16/5 × 3/4 × (-8/3)
= 192/60 × 45/60 × (-160/60) = - 1382400/216000 = 6 87/216
