Toko bu amat mempunyai persediaan minyak tanah 5 1/2 drum.Pada hari pertama terjual 3/4 drum.Pada hari kedua terjual 2,2 drum.Pada hari ketiga persediaan minyak

Diketahui :
Persediaan 1 = 5 ½ drum
Terjual 1 = ¾ drum
Terjual 2 = 2,2 drum
Persediaan 2 = 3 ¼ drum

Ditanya :
Persediaan Total = ???

Dijawab :
P. Total = P1 - T1 - T2 + P2
P. Total = 5½ - ¾ - 2,2 + 3¼
P. Total = 5,5 - 0,75 - 2,2 + 3,25
P. Total = 5,8 drum

5,8 = 58/10 = 5 8/10 = 5 4/5 drum
Jawaban B

[tex] = 5 \frac{1}{2} - \frac{3}{4} - 2.2 + 3\frac{1}{4} \\ = \frac{11}{2} - \frac{3}{4} - \frac{22}{10} + \frac{13}{4} \\ = \frac{110}{20} - \frac{15}{20} - \frac{44}{20} + \frac{65}{20} \\ = \frac{110 - 15 - 44 + 65}{20} \\ = \frac{116}{20} \\ = 5 \frac{16}{20} \\ = 5 \frac{4}{5} [/tex]
