Answer

70

Work Step by Step

42$\div$0.6 Move the decimal in 0.6 to make it a whole number (6). To accommodate for this, add one per to 42 (420). 420$\div$6 Use long division to divide this, and the answer will be 70. Alternatively, notice that 42$\div$6 = 7, and that 420 = 42 * 10, so 420$\div$6 = 7 * 10 = 70.
