Question

(-0,2)^-1x10^-2+0,125:10^-1-0,1(6)x3,(6)

Answer 1

Explicație pas cu pas:

(-0,2)^-1 • 10^-2 + 0,125 : 10^-1 - 0,1(6) • 3,(6) =

(-2/10)^-1 • 1/10^2 + 125/1000 : 1/10 - (16-1)/90 • (36-3)/9 =

(-1/5)^-1 • 1/100 + 1/8 • 10 - 15/90 • 33/9 =

- 1/(1/5) • 1/100 + 10/8 - 1/6 • 11/3 =

- 5 • 1/100 + 5/4 - 11/18 =

- 1/20 + 5/4 - 11/18 =

- 9/180 + 5•45/180 - 11•10/180 =

( - 9 + 225 - 110)/180 =

106/180 =

53/90 =

0,5(8)
