Aduh Soal INi bikin aku pusing

1.pecahan campuran hasil dari 2,5x75%-2/5

2.hasil 12,5% x(3/4+1/8x40%)dalam bentuk pecahan biasa

Answer 1

25/10 x 75/100 - 2/5
= 1875/1000 - 2/5
= 1875 - 800/1000
= 1075/1000
= 1 75/1000 = 1 3/40

125/1000 x (3/4 + 1/8 x 40/100 )
=5/40 x (3/4 + 5/100)
=5/40 x (75/100 + 5/100 )
=5/40 x 80/100
=400/4000
=1/10
