Question

Me ajudem por favor???
2-0,5+1/2+3/4=

Answer 1

2-0,5+1/2+3/4=
mmc ( 10-2-4)=>20

$2 - \frac{5}{10} + \frac{1}{2} + \frac{3}{4} \\ \\ \frac{2}{1} - \frac{5}{10} + \frac{1}{2} + \frac{3}{4} \\ \\ \frac{40 - 10 + 10 + 15}{20} \\ \\ \frac{55}{20 } = > \frac{11}{4}$

Answer 2

Olá!!!

Resolução!!!

= 0,5 → 1/2

= 2 - 0,5 + 1/2 + 3/4
= 2 - 1/2 + 1/2 + 3/4

mmc ( 2, 2, 4 ) = 4

= 8/4 - 2/4 + 2/4 + 3/4
= ( 8 - 2 + 2 + 3 )/4
= ( 6 + 2 + 3 )/4
= ( 8 + 3 )/4
= 11/4

R = 11/4

Espero ter ajudado!!!
