Answer 1

Sper să-ți fie de folos.

Answer 2

a = $(\frac{1}{3} + \frac{1}{5} ) :\frac{1}{2}$

a = $(\frac{5}{15} + \frac{3}{15} ) :\frac{1}{2}$

a = $\frac{8}{15} :\frac{1}{2} = \frac{8}{15} *\frac{2}{1}$

a = $\frac{16}{15}$

b = $(\frac{1}{3} - \frac{1}{5})*\frac{1}{2}$

b = $(\frac{5}{15} - \frac{3}{15})*\frac{1}{2}$

b = $\frac{2}{15}*\frac{1}{2}$

b = $\frac{1}{15}$

a = 16 * b

Deci a este de 16 ori mai mare decat b
