Jawablah dgn 3 jawaban (pecahan, desimal ,persen,

Penjelasan dengan langkah-langkah:

1) ½ + 2,25 – 3/4

= ½ + 225/100 – 3/4

= 50/100 + 225/100 – 75/100

= 275/100 – 75/100

= 200/100

= 200% (persen)

= 8/4 (pecahan)

= 2 (desimal)

2) 75% – 0,25 + 2 1/4

= 75/100 – 25/100 + 9/4

= 75/100 – 25/100 + 225/100

= 50/100 + 225/100

= 275/100

= 275% (persen)

= 11/4 (pecahan)

= 2,75 (desimal)

Penjelasan dengan langkah-langkah:

1. 1/2 + 2,25 – 3/4 =

= 1/2 + 225/100 – 3/4

= 50/100 + 225/100 – 75/100

= 275/100 – 75/100

= 200/100 atau 2/1 (Pecahan)

= 2 (Desimal)

= 2% (Persen)

2. 75% – 0,25 + 2 1/4

= 75/100 – 25/100 + 9/4

= 75/100 – 25/100 + 225/100

= 50/100 + 225/100

= 275/100 atau 2 75/100 atau sederhana nya 2 3/4 (Pecahan)

= 2,75 (Desimal)

= 2,75% (Persen)
