2800.
7 x 420 = 7(400 + 20) = 7 * 400 + 7 * 20.
1/5 x 400 = 80
2 x 4 -1 =7 7 x 4 - 2 = 26 26 x 4 - 3 = 101 101 x 4 - 4 = 400 400 x 4 - 5 = 1600 - 5 = 1595 So, the next number is 1595
7 x 400 = 2800
60,427 = (6 x 104) + (0 x 103) + (4 x 102) + (2 x 101) + (7 x 100)
7 x 420 = 7(400 + 20) = 7 * 400 + 7 * 20.
7 x 420 = (7 x 400) + (7 x 20)
7 x 420 = (7 x 400) + (7 x 20)
7 x 400 + 7 x 20 _________ 2940
1/5 x 400 = 80
2 x 4 -1 =7 7 x 4 - 2 = 26 26 x 4 - 3 = 101 101 x 4 - 4 = 400 400 x 4 - 5 = 1600 - 5 = 1595 So, the next number is 1595
7 x 1 = 7 7 x 57 = 399 There are 57 of them.
7 x 400 = 2800
