42 per 5 dikurangi 40% tambah 1 1/4 =

[tex] \frac{42}{5} - 40\% + 1 \frac{1}{4} \\ = \frac{42}{5} + \frac{40}{100} + \frac{5}{4} \\ = \frac{840 + 40 + 125}{100} \\ = \frac{1005}{100} \\ = 10 \frac{5}{100} \\ = 10 \frac{1}{20} [/tex]
Semoga bisa membantu..

42/5-40%=900/100-40/100=860/100+5/4=860/100+125/100=211/100=211%=2.11=10 1/20
