Răspuns:

Explicație pas cu pas:

3/4*(2/5 + 7/3) = 3/4*(6/15 + 35/15) = 3/4*41/15 = 41/20

sau

3/4*(2/5 + 7/3) = 3/4*2/5 + 3/4*7/3 = 6/20 + 7/4 = 6/20 + 35/20 = 41/20

____________

2/5*(3/4 + 5/8) = 2/5*(6/8 + 5/8) = 2/5*11/8 = 11/20

sau

2/5*(3/4 + 5/8) = 2/5*3/4 + 2/5*5/8 = 6/20 + 5/20 = 11/20

____________

4/7*(3/2 + 21/4) = 4/7*(6/4 + 21/4) = 4/7*27/4 = 27/7

sau

4/7*(3/2 + 21/4) = 4/7*3/2 + 4/7*21/4 = 6/7 + 21/7 = 27/7
