2*(2/3)= (2/1)*(2/3)=(2*2)/(1*3)=4/3

si

(15/7)*14= (15/7) * (14/1)=(15*14)/(7*1) = (15*14)/7= simplificam prin 7 =(15*2)/1=30

atunci calcululcerut este

4/3+30=1si1/3=30=31si1/3= (93+1)/3=94/3
2×2/3+15/7×14=

4/3+210/7=

[tex] \frac{4}{3} + \frac{210}{7} ^{7} = \frac{4}{3} + \frac{30}{1} ^{3} = \frac{4}{3} + \frac{90}{3} = \frac{94}{3} [/tex]
