Question

Urgent va rogg dau coroniță

Answer 1

Răspuns:

Explicație pas cu pas:

4/5 + 1/2 = 8/10 + 5/10 = 13/10

5/13*13/10 = 5/10 = 1/2

(3/2)^2 = 9/4

1/2 : 9/4 = 1/2*4/9 = 2/9

2/3 : 2/9 = 2/3*9/2 = 3

Answer 2

Explicație pas cu pas:

ღSalutare!ღ

2/3:[5/13×(4/5+1/2):(3/2)²]=

=2/3:[5/13×(8/10+5/10):9/4]=

=2/3:(5/13×13/10:9/4)=

=2/3:(65/130:9/4)=

=2/3:(65/130×4/9)=

=2/3:(260/1170)=

=2/3×1170/260=

=2340/780(simplificam prin 780)=>3/1=3✅

"/"=linie de fracție

Succes!!;)
