Question

cred ca e simpla dar ma tot încurc la ea . va rog . multumesc

Answer 1

$\frac{360 \times 125}{450} = 100 \: grade \\ \\ \frac{360 \times 100}{450} = 80 \: grade \\ \\ \frac{360 \times 75}{450} = 60 \: grade \\ \\ \frac{360 \times 150}{450} = 120 \: grade \\ \\ 120 + 60 + 80 + 100 = 360 \: \\ deci \: se \: verifica \: calculul \: facut$
$\frac{75 \times 100}{450} = 16.66\% \\ \\ \frac{100 \times 100}{450} = 22.22\% \\ \\ \frac{125 \times 100}{450} = 27.77\% \\ \\ \frac{150 \times 100}{450} = 33.33\% \\ \\ 33.33 + 27.77 + 22.22 + 16.66 = \\ 99.98(100\%) \: se \: verifica$
cam astai tot...sper sa imi dai o coroana. mio luat ceva sa scriu astea in format formula
