1. 120: 10 x (-2) + (-16) =...
2. 65%+0,25+¼=....
3. 125+(24×50)=....
jwb dengan langkah² nya​

Jawaban:

Nomor 1

• 120 ÷ 10 × (-2) + (-16)
• = 12 × (-2) + (-16)
• = -24 + (-16)
• = -40

Nomor 2

• 65% + 0,25 + ¼
• = 65/100 + 0,25 + ¼
• = 0,65 + 0,25 + 1 × 25/4 × 25
• = 0,65 + 0,25 + 25/100
• = 0,65 + 0,25 + 0,25
• = 0,90 + 0,25
• = 1,15

Nomor 3

• 125 + (24 × 50)
• = 125 + (24 × 5)0
• = 125 + 1.200
• = 1.325

Penjelasan dengan langkah-langkah:

1. 120 ÷ 10 × (-2) + (-16) =

=12×(-2) + (-16)

=(-24) + (-16)

= (-40) ✓

2. 65% + 0,25 + 1/4 =

[tex] = \frac{261}{4} + \frac{1}{4} [/tex]

[tex] = \frac{(261 + 1)}{4} [/tex]

[tex] = \frac{262}{4} [/tex]

[tex] = \frac{131 \times 2}{2 \times 2} [/tex]

[tex] = \frac{131}{2} [/tex]

[tex] = \bf65 \frac{1}{2} [/tex]

3. 125 +(24×50) =

Dahulukan Perkalian!

=1.200 + 125

= 1.325 ✓

Cara No 3 Terlampir!
