Question

1).(10+1 supra 6) : ( 1 intreg 1 supra 5 + 1 supra 20)
2. 17 intregi 1 supra 4 + ( 5 intregi 1 supra 2 - 1 intreg 1 supra 5) + 1 supra 20

Answer 1

1) (10+1/6) : ( 1 intreg 1/5 + 1/20)=
=(60+1)/6 : (6/5+1/20)=
=61/6 : (24+1)/20=
=61/6 : 25/20=
=61/6 × 4/5=
=122/15

2. 17 intregi 1/4 + ( 5 intregi 1/2 - 1 intreg 1/5) + 1/20=
= 69/4 + (11/2 - 6/5) + 1/20=
= 69/4 + (55-12)/10 + 1/20=
= 69/4 + 43/10 + 1/20=
=(345+86+1)/20=
=432/20=216/10=108/5=21,6
