5 is half of 10 so the answer will be half of 420, which is 210.
That's easy, just half it. 420 divided by 2 (5 is half of 10) which equals 210. (1) To check my answer, I did... 42 x5 (5 x 2=10 (carry the one), then 5 x 4=20 + 1= 120) ---- 210
10% of 420 is 42.
42 x 10 = 420
With a calculator this can be done by doing 420*1.11.Without a calculator, it is also very easy, and is done by finding 10% of 420 which is 420/10 which is 42. So 42 = 10% of 420. And 1% of 420 is 4.2. 1%+10%+100% = 4.2+42+420 =466.2.466.2Very basic.:)
42 is 10% of 420.
you would take the answer 420 and split in half
