a) 64% : y = 8

y = 16/25 : 8
y = 2/25
b) y x 100 = 75%
y x 100 = 3/4
y = 3/4 : 100

64% : y = 8
=> 64/100 : y = 8
=> y = 64/100 : 8
=> y = 2/25 = 0,08
y x 100 = 75%
=> y x 100 = 75/100
=> y = 75/100 : 100
=> y = 3/400
\(64\%:y=8\)
\(\frac{16}{25}:y=8\)
\(y=\frac{16}{25}:8\)
\(y=\frac{2}{25}\)
\(y\cdot100=\frac{75}{100}\)
\(y\cdot100=\frac{3}{4}\)
\(y=\frac{3}{4}:100\)
\(y=\frac{3}{400}\)
\(64\%\div y=8\) ; \(y\div100=75\%\)
\(0,64\div y=8\) \(y\div100=0,75\)
\(y=0,64\div8\) \(y=0,75\times100\)
\(y=0,08\) \(y=75\)
