Answer 1

Răspuns:

Explicație pas cu pas:

a) 5·(4/15)=4/3

b) (21/70)·(42/18)=(3/10)·(21/9)=7/10    

c) (4/15)·(60/16)·(12/20)=(4·60·12)/(15·16·20)=(4·3·12)/(15·16)=(3·12)/(15·4)=

12/(5·4)=3/5

d) 2 3/4·1 5/22=(11/4)·(27/22)=(11·27)/(4·22)=27/4·2=27/8  

e) 9 2/14·(42/128)·11 1/3=(128/14)·(42/128)·(34/3)=(128·42·34)/(14·128·3)=(42·34)/(14·3)=(42·34)/42=34  

f) (3/5)·(2/7)·(21/18)=(3·2·21)/(5·7·18)=21/(5·7·3)=21/(5·21)=1/5  

g) (2²/3²)·(3/24)=(4·3)/(9·24)=3/(9·6)=1/(3·6)=1/18  

h) [(2³·3)/(4·5)]·[(2²·3²)/(3·7)]=(6/5)·(12/7)=(6·12)/(5·7)=72/35
