Question

in 5 lazi erau 280kg de rosii.Cate kilograme de rosii erau in 8 lazi? dar in 6 lazi?

Answer 1

$5 \: lazi \: .....280 \: kg \\ 8 \: lazi \: ..... \: x \: kg$

$x = \frac{280 \times 8}{5} = 56 \times 8 = 448 \: kg$

$5 \: lazi \: ..... \: 280 \: kg \\ 6 \: lazi \: ..... \: y \: kg$

$y = \frac{280 \times 6}{5} = 56 \times 6 = 336 \: kg$

Answer 2

5 lazi .................. 280 kg
1 lada ................. x kg

x = 1 x 280 / 5 = 280  / 5 = 56 kg ( rosii intr-o lada )


1 lada ................. 56 kg
8 lazi ................... x kg

x = 8 x 56 / 1 = 448 / 1 = 448 kg ( rosii in 8 lazi )

1 lada ................... 56 kg
6 lazi ....................... x kg

x = 6 x 56 / 1 = 336 / 1 = 336 kg ( rosii in 6 lazi )
