Since 10 percent of 45 is 4.50, 5 percent of 45 will be half that amount, or 2.25, and 15 percent will be the sum of those two figures, or 6.75 (4.50 + 2.25 = 6.75).
10 procenti no 45 būs 4,50, 5 procenti no 45 būs puse no 4,50, t.i., 2,25, un 15 procenti būs iegūto skaitļu summa, t.i., 6,75 (4,50 + 2,25 = 6,75).
