Answer 1

Jawaban:

Penyelesaian :

[tex] \sf 6 \frac{3}{4} + \frac{1}{2} - 5 \frac{2}{3} [/tex]

[tex] \sf = \frac{27}{4} + \frac{1}{2} - \frac{17}{3} [/tex]

[tex] \sf = \frac{(27 \: \times \: 3)}{12} + \frac{(1 \times 6)}{12} - \frac{(17 \times 4)}{12} [/tex]

[tex] \sf = \frac{81}{12} + \frac{6}{12} - \frac{68}{12} [/tex]

[tex] \sf = \frac{87}{12} - \frac{68}{12} [/tex]

[tex] \sf = \frac{19}{12} [/tex]

[tex] \sf = 1 \frac{7}{12} [/tex]

Answer 2

( 6 3/4 + 1/2 ) - 5 2/3 =

= ( 27/4 + 1/2 ) - 17/3

= ( 27×2/4×2 + 1×4/2×4 ) - 17/3

= ( 54/8 + 4/8 ) - 17/3

= ( 58/8 ) - 17/3

= 58/8 - 17/3

= 58×3/8×3 - 17×8/3×8

= 174/24 - 136/24

= 38/24

= 19/12

= C. 1 7/12
