Question

cat e
$( \frac{4}{9} + \frac{5}{9} ) - \frac{4}{6}$
​

Answer 1

Răspuns:

Explicație pas cu pas:

( 4/9 + 5/9 ) - 4/6 = 9/9 - 2/3 = 1 - 2/3 = 3/3 - 2/3 = 1/3

4/9 + 5/9 = (4+5)/9 = 9/9 = 1 intreg

4/6 = (4:2)/(6:2) = 2/3 -> am simplificat fractia cu 2

1 - 2/3 -> scriu intregul ca fractie 3/3 ( numitor 3)
