Question

Решите примеры пропорцием

Answer 1

1)6--480
2--X
$x = frac{480 times 2}{6} \ x = 160$

2)6--4
12--X
$x = frac{12 times 4}{6} = 8$
$8 times 3 = 24$
3)5--8
10--X
$x = frac{10 times 8}{5 } = 16$
$16 times 1 = 16$

Answer 2

1)6--480

2--X

x = 480•2/6=160

2)6--4

12--X

x = 12•4/6=8

8 •3 = 24

3)5--8

10--X

x = 10•8/5=16

16 • 1 = 16
