y=270,3125

Sper ca te-am ajutat ☺️

Answer 2

Răspuns:

x=(2,1-1,19)÷4+45

x=(21/10- 119/100):4 +45

x= (210/100- 119/100)×1/4+45

x= 91/100×1/4+45

x= 91/400+45

x= 91/400+ 18000/400

x= 18091/400

x= 45,2275

y=(2,3+15)×12,5÷(2,05-1,25)

y=( 23/10+15)×125/10: (205/100-

125/100)

y=( 23/10+150/10)×125/10: 80/100

y= 173/10×125/10×100/80

y= 173/10× 25/2×5/4

y= 4325/16

y= 270,3125
