Question

Salut am nevoie de putin ajutor la:
1) cum rezolvi 6 $\frac{9}{16}$ 
2) cum rezolvi: 6 $\frac{9}{16}$ - 2 $\frac{1}{2}$ x 1 $\frac{9}{14}$
(x fiind inmultire)

Answer 1

1.
6 intregi si 9/16=(6×16+9)//16=(96+9)/16=105/16

2.
 2 1/2=(2×2+1) /2=5/2
1 9/14=(1×14+9) /14=23/14
 6 9/16- 2 1/2 × 1 9/14=105/16+5/2×23/14 =105/16-115/28=
aducem la acelasi numitor care este  112
=(105×7-115×4)/112=(735-460)/112=275/112
