Question

Am nevoie de ajutor la ex7si 8 dau coroana promit !!!!!!!!!!❤

Answer 1

(19+81)×(27+33):30=100×60:30=6000:30=200
[1000+(1000-1000:10)]:100×1=
=[1000+(1000-100)]:100×1=(1000+900):100×1=
=1900:100×1=19×1=19
a) 200>19

b). 32×(25+35:5)-24=32×(25+7)-24=
=32×32-24=1024-24=100

100+[24×(100+100:10)]:10=
=100+[24×(100+10)]:10=
=100+(24×110):10=
=100+2640:10=
=100+264=364

b). 1000>364

Problema 8

2×50=100 tarte vișine
2×400=800 tarte caise
2×30=60 tarte zmeura
100+80+60=240 total tarte
Câte tarte au fost așezate pe fiecare platou ?
240:15=16 tarte

[(2×50)+(2×400)+(2×30)]:15=
100+80+60):15=
=240:15=16 tarte
R=16 tarte

Sau : (2×50+2×40+2×30):15=
=(100+80+60):15=
=240:15=16
