Question

Efetue as equações
A- 0,35555 + 0,23333
B- 3,4444 - 2,6666

Answer 1

0,3555............. = ( 35-3)/90  = 32/90= 16/45 ***
0,2333...............= ( 23 -2)90 = 21/90 = 7/30 ***
16/45 + 7/30 = 
mmc = 90
( 32 + 21)/90 = 53/90 ****

b
3,444.....  (34 - 3 )/9  = 31/9 ***
2,666.....  ( 26-2)/9 = 24/9 =8/3 ***
31/9 - 8/3 = 
mmc= 9
( 31 - 24)/9 = 7/9 ***
