tolng ya no 9 dan 10 pake cara,syukron

9.
[tex] = 0.6 + 2 \frac{1}{4} - 1.25 \\ = \frac{6}{10} + \frac{9}{4} - \frac{125}{100} \\ = \frac{60}{100} + \frac{225}{100} - \frac{125}{100} \\ = \frac{285}{100} - \frac{125}{100} = \frac{160}{100} = 1.6kg[/tex]
Jadi, sisa gula pasir Bu Anti adalah 1,6 kg

Mf saya hnya bsa kerjakan no 9, semoga membantu ya:)

9.) Cara ke-1
=0,6+2 1/4-1,25
=6/10+9/4-1 25/100
=6/10+9/4-125/100
=60/100+225/100-125/100
=285/100-125/100
=160/100
=8/5
=1 3/5

Cara ke-2
=0,6+2 1/4-1,25
=0,6+2,25-1,25
=2,85-1,25
=1,6

1 3/5 nilai nnya sama dengan 1,6

10.)= (1,2-1/4):0,18
=(1 2/10-1/4):18/100
=(12/10-1/4):18/100
=(24/20-5/20):18/100
=19/29×100/18
=1900/522
=3 334/522
=3 167/261

Maaf kalo salah
