Răspuns:

Explicație pas cu pas:

a) $\frac{3}{10} * 400 = \frac{3*400}{10} = \frac{3*40}{1} = 120$

400+120 = 520

b) $\frac{4}{5} * 400 = \frac{4*400}{5} = \frac{3*80}{1} = 240$

400+240 = 640

c) $\frac{25}{100} * 400 = \frac{25*400}{100} = \frac{25*4}{1} = 100$

400+100 = 500

d) $\frac{3}{8} * 400 = \frac{3*400}{8} = \frac{3*50}{1} = 150$

400+150 = 550

e) $\frac{13}{16} * 400 = \frac{13*400}{16} = \frac{3*25}{1} = 75$

400+75 = 475
