Question

Efectuati : d) (9 - 1,8) (4,3 x 0,5 + 1,25 x 0,1) : 10^2 e) 3,01 x (4,3:0,4-5,3:0,5-0,7x0,1) f) 432,29:(3,5x0,5+4,3:0,01+5,4x0,1)

Answer 1

(9-1,8)(4,3×0,5+1,25×0,1):10²=
=8,8(2,15+0,125):100=
=8,8×0,26875:100=
=2,365:100=
=236,5

3,01×(4,3:0,4-5,3:0,5+0,7×0,1)=
=3,01×(10,75-10,6+0,07)=
=3,01×(10,15+0,07)=
=3,01×10,22=
=30,7622

432,29:(3,5×0,5+4,3:0,01+5,4×0,1)=
=432,29:(1,75+430+0,54)=
=432,29:432,29=
=1
