Question

ex 7 b, d
Va rog frumos ​

Answer 1

Răspuns:

Explicație pas cu pas:

7) b) (2 1/2)/4 = x/(1 3/4)  <=>

(5/2)/4 = x/(7/4) =>

x = (5/2 · 7/4) :4 =>

x = 35/8 · 1/4 =>

x = 35/32

d) (3/8) /(2/5) = x/(1 2/3) <=>

(3/8)·(5/2) = x/(5/3) <=>

15/16 = x·3/5 =>

x = (15·5)/(16·3) =>

x = 25/16
