tolong dijawab plissssss

...............................

[tex]4\frac{1}{2} - 2 \frac{6}{12} = \frac{9}{2} - \frac{30} {12} = \frac{18 - 30}{12} \div (2\frac{1}{2} + 1 \frac{1}{4}) = ( \frac{5}{4} + \frac{5}{4} ) = ( \frac{10}{4} + \frac{5}{4} ) = \frac{15}{4} = \frac{9}{12} - \frac{30}{12} \times \frac{4}{15} = \frac{9}{12} - \frac{120}{180} = \frac{9}{2} - \frac{2}{3} = \frac{27}{6} - \frac{4}{6} = (27 - 4)6 = \frac{23}{6} = 3 \frac{5}{6} [/tex]
jadi jawabannya yang B. 3 5/6

semoga jawabannya betul dan maaf kalo salah ^_^
