Question

calcule e simplifique se possivel 2,2/5+11/2+1/3

Answer 1

Podemos fazer de 2 modos

1° modo

$\frac{2,2}{5} + \frac{11}{2} + \frac{1}{3} = \\ \\ mmc(5,2,3)=30 \\ \\ \frac{6.(2,,2)+15(11)+10}{30} = \\ \\ \frac{13,2+165+10}{30} = \\ \\ \frac{188,2}{30} = \\ \\ \frac{1882}{10}\div30= \\ \\ \frac{1882}{10} \times \frac{1}{30} = \frac{1882}{300} = \frac{941}{150}$

2° modo

$\frac{22}{10} \div5 + \frac{11}{2} + \frac{1}{3} = \\ \\ \frac{11}{5} . \frac{1}{5} + \frac{11}{2} + \frac{1}{3} = \\ \\ \frac{11}{25} + \frac{11}{2} + \frac{1}{3} = \\ \\ mmc(25,2,3)=300 \\ \\ \frac{132+1650+100}{300} = \frac{1882}{300}= \frac{941}{150}$
