Diketahui a= 2 1/5 b = 6 1/2 c = 3 1/4 nilai a-b:c Pakai cara

[tex]dik \: \\ a = 2 \frac{1}{5} \\ b = 6 \frac{1}{2} \\ c = 3 \frac{1}{4} \\ \\ \\ dit \: a - b \div c \\ \\ jawab \\ [/tex]
[tex]2 \frac{1}{5} = \frac{11}{5} \\ 6 \frac{1}{2} = \frac{13}{2} \\ 3 \frac{1}{4} = \frac{13}{4} \\ \\ \frac{11}{5} - \frac{13}{2} \div \frac{13}{4} \\yg \: dikerjakan \: pembagian \: dulu \\ = \frac{13}{2} \div \frac{13}{4} \\ = \frac{13}{2} \times \frac{4}{13} \\ = \frac{52}{26} \\ lanjutkan \: pengurangannya \\ = \frac{11}{5} - \frac{52}{26} \\ = \frac{ - 41}{ - 21} \\ = 1 \frac{20}{21} [/tex]

semoga membantu yaa
