Hitunglah nilai dari operasi campuran berikut 2/3 - 5% : 4/5 + 3/4 x 0,15 ( di buat perseratus)

2/3 - 5% : 4/5 + 3/4 x 0,15

= 2/3 - (5/100 : 4/5) + (3/4 x 15/100)

= 2/3 - (5/100 x 5/4) + 45/400

= 2/3 - 1/8 + 9/80

= 160/240 - 30/240 + 27/240

= 130/240 + 27/240

= 157/240

jawaban:

2 1/108

Penjelasan dengan langkah-langkah:

1/2 : 3/4 - 5/9 + 3/4 × 2 1/3 = 1/2 : 3/4 = 1/2 × 4/3 = 4/6

4/6 - 5/9 = 12-10/18 = 2/18

2/18 + 3/4 = 4+27/36 = 31/36

31/36 × 2 1/3 = 31/36 × 7/3 = 217/108 = 2 1/108

semoga membantu,saya jawab sesuai kemampuan saya ya,maaf kalau ada yang salah.

Nilai dari operasi campuran berikut!

2/3-(5%:4/5)+(3/4×0,15)

= 2/3 - (5/100 x 5/4) + (3/4 x 15/100)

= 2/3 - (25/400) + (45/400)

= 800/1200 - 75/1200 + 135/1200

= 860 /1200

=86/120

=43/60 = 0,72

Penjelasan dengan langkah-langkah:

Selesaikan perkalian dan pembagian dahulu

Penjelasan dengan langkah-langkah:

1. 25/7 + 3/7 = 28/7 = 4

2. 24/9 - 7/3 = 24/9 - 21/9= 3/9=1/3

3. 12/5 × 5/8 = 60/40 =6/4 = 1 2/4

4. 4/5 ÷ 32/4 = 4/5 ÷ 8 = 4/5 × 1/8 = 4/40 =1/10

5. a. 1/3 ÷ 3/4 - 5/9 + 3/4 × 21/3

= 1/3 × 4/3 - 5/9 + 3/4 × 7

= 4/9 -5/9 + 21/4

= -1/9 + 21/4

= -4/36 + 189/36

= 185/36

=5 5/36

b. 2/3 - 5 % ÷ 4/5 + 3/4 × 0.15

= 2/3 -5/100 × 5/4 + 3/4 × 15/100

= 2/3 - 1/20 × 5/4 + 3/4 × 3/20

= 2/3 - 5/80 + 9/80

= 2/3 - 14/80

= 2/3 - 7/40

= 80/120 -21/120

=59/120
