Question

CALCULEAZA DEIMPARTITUL: a:4=83 b:(2x3)=119-42; c:(3x42-12x10)=85x2; d:(2x3x7)=9.va rog multtt e urgent.

Answer 1

a : 4 = 83

a = 83 × 4

a = 332 → deimpartitul

Verific:  332 : 4 = 83

___________________

b : ( 2 × 3 ) = 119 - 42

b : 6 = 77

b = 77 × 6

b = 462

Verific:   462 : 6 = 77

__________________

c : ( 3 × 42 - 12 × 10 ) = 85 × 2  

c : ( 126 - 120 ) = 170

c : 6 = 170

c = 170 × 6

c = 1 020 → deimpartitul

____________

d : ( 2 × 3 × 7 ) = 9

d : 42 = 9

d = 9 × 42

d = 378 → deimpartitul

Answer 2

a:4=83

a=4X83

a=332

b:(2X3)=119-42

b:6=77

b=6X77

b=462

c:(3X42-12X10)=85X2

c:(126-120)=170

c:6=170

c=170X6

c=1020

d:(2X3X7)=9

d=(6X7)=9

d:42=9

d=42X9

d=378
