1. 8 3/4 + 4 7/8?
2. 11 + (-23)?
3. 5 2/3 - 2 1/6 + 3 3/4?
TOLONG JAWAB SEKARANG YAA MAKASIHH​

1.) 8¾ + 4⅞

= 35/4 + 39/8

= 70/8 + 39/5

= 109/8

= 13⅝

2.) 11 + (-23)

= -(23 - 11)

= -12

3.) 5⅔ - 2⅙ + 3¾

= 17/3 - 13/6 + 15/4

= 68/12 - 26/12 + 45/12

= 87/12

= 7 3/12

= 7¼

Jawaban:

[tex]1. \: \: 13 \frac{5}{8} [/tex]

2. -12

[tex]3. \: \: 7 \frac{1}{4} [/tex]

Penjelasan dengan langkah-langkah:

[tex]1. \: \:8 \frac{3}{4} + 4 \frac{7}{8} = \frac{35}{4} + \frac{39}{8} \\ = \frac{70}{8} + \frac{39}{8} \\ = \frac{109}{8} = 13 \frac{5}{8} [/tex]

2. 11 + (-23) = -12

3.

[tex]3. \: \: 5 \frac{2}{3} - 2 \frac{1}{6} + 3 \frac{3}{4} \\ = \frac{17}{3} - \frac{13}{6} + \frac{15}{4} \\ = \frac{68}{12} - \frac{26}{12} + \frac{45}{12} \\ = \frac{87}{12} = 7 \frac{3}{12} \\ = 7 \frac{1}{4} [/tex]
