Question

x ori 37/10 = 0,2 ori 30 ori ( 2intreg 2/3 + 7/15

Answer 1

x * 37/10=2/10 *30* (2*2/3+7/15)⇒x*37/10=2/10*30*(4/3+7/15)
in paranteza amplificam prima fractie cu 5 ⇒
x*37/10 = 2/10 *30*(20/15+7/15)⇒x*37/10=2/10*30*27/15
simplificam 30 cu 15 prin 15⇒
x*37/10=2/10*2*27⇒x*37/10=108/10⇒x=108/10:37/10⇒x=108/10*10/37
se reduce 10 cu 10⇒x=108/37
