Răspuns:

(2.92 - 2.304 - 0.112·0.5) : 7 =

= (292/100 - 2340/1000 - 112/1000×1/2)×1/7

= (2920/1000 - 2340/1000 - 56/1000)×1/7

= 560/1000×1/7

= 14/25×1/7

= 2/25

= 8/100

= 0,08

[ 12,5 : 100 + 7,5(0,06 + 1,8²) - 4:10 =

= [ 125/10×1/100 + 75/10(6/100 + 18²/10²)] - 4/1×1/10

= [ 125/1000 + 75/10(6/100 + 324/100) - 4/10

= (125/1000 + 75/10×330/100) - 400/1000

= (125/1000 + 24750/1000) - 400/1000

= (125+24750-400)/1000

= 24475/1000

= 2,4475
