Question

Maria si colegii ei au participat la diverse experimente.Efectueaza calculele,apoi asociaza rezultatele cu literele corespunzatoare.Asezand rezultatele in ordine crescatoare,vei descoperi ce i-a placut Mariei. Ajutațimă dau puncte si coroană! g ..h va rog urgent.

Answer 1

Răspuns: $\bf \orange{P~L~U~T~I~R~E~A}$ este experimentul ce i-a plăcut Mariei

Explicație pas cu pas:

$\bf A) ~15 + 15:15 \cdot (15 + 15 \cdot 15)=$

$\bf 15 + 15:15 \cdot (15 + 225)=$

$\bf 15 + 15:15 \cdot 240=$

$\bf 15+1\cdot240=$

$\bf 15+240=\pink{\underline{\underline{255}}}$

$\bf -----------------$

$\bf B) ~250 + 60 : (50 - 2 \cdot 15) \cdot 50=$

$\bf250 + 60 : (50 - 30) \cdot 50=$

$\bf250+3\cdot50=$

$\bf 250+150=\purple{\underline{\underline{400}}}$

$\bf -----------------$

$\bf C)~ 110:10 \cdot (110 - 20 \cdot 4) + 670=$

$\bf 110:10 \cdot (110 - 80) + 670=$

$\bf 11\cdot30+670=$

$\bf 330+670=\blue{\underline{\underline{1000}}}$

$\bf -----------------$

$\bf D)~ (444: 4 + 400 - 400:10): 3=$

$\bf (111 + 400 - 40): 3=$

$\bf (511-40):3=$

$\bf 471:3=\green{\underline{\underline{157}}}$

$\bf -----------------$

$\bf E)~ 100 - 100 : 100 \cdot [ 100 + 100: 10 - (100 - 75: 25)]=$$\bf 100 - 100 : 100 \cdot [ 100 + 10 - (100 - 3)]=$$\bf 100 - 100 : 100 \cdot ( 100 + 10 - 97)=$$\bf 100 - 100 : 100 \cdot ( 110 - 97)= 100 - 100 : 100 \cdot 13=$

$\bf 100 - 1 \cdot 13=$

$\bf 100-13=\orange{\underline{\underline{87}}}$

$\bf -----------------$

$\bf F)~ 50 + 12 \cdot [ 214 - 240 : ( 16 - 2 \cdot 5)] - 10 \cdot 100=$$\bf 50 + 12 \cdot [ 214 - 240 : ( 16 - 10)] - 10 \cdot 100=$$\bf 50 + 12 \cdot ( 214 - 240 : 6 ) - 10 \cdot 100=$

$\bf 50 + 12 \cdot ( 214 - 240 : 6 ) - 10 \cdot 100=$

$\bf 50 + 12 \cdot ( 214 - 40 ) - 10 \cdot 100=$

$\bf 50 + 12 \cdot 174 - 10 \cdot 100=$

$\bf 50+2088-1000=$

$\bf 2138-1000=\red{\underline{\underline{1138}}}$

$\bf -----------------$

$\bf G) ~110 \cdot 10 - [( 599-99 \cdot 4 + 30 \cdot 5) + 370:10]: 10=$$\bf 110 \cdot 10 - [( 599-396 + 150) + 370:10]: 10=$$\bf 110 \cdot 10 - ( 353 + 370:10): 10=$

$\bf 110\cdot10- ( 353 + 37): 10=$

$\bf 110\cdot10- 390: 10=$

$\bf 1100-39=\purple{\underline{\underline{1061}}}$

$\bf -----------------$

$\bf H) ~(9\cdot 999 - 999:9): 10 - [444-6-(400 - 400 : 10)] =$$\bf (8991 - 999:9): 10 - [444-6-(400 - 40)] =$$\bf (8991 - 111): 10 - [444-6-(400 - 40)] =$$\bf8880: 10 - [444-6-(400 - 40)] =$

$\bf888 - (444-6-360) =$

$\bf 888-78=\pink{\underline{\underline{810}}}$

$\bf -----------------$
