Question 1 Find all multiples of 40 that lie between 310 and 410.We know that 40 × 10 = 400, and 40 × 11 = 440 So, let’s find multiples of 40 by multiplying from around 6 to 10 40 × 6 = 240 40 × 7 = 280 40 × 8 = 320 40 × 9 = 360 40 × 10 = 400 40 × 11 = 440 Thus, all multiples of 40 that lie between 310 and 410 are 320, 360, 400
