420 = (4 x 100) + (2 x 10) + (0 x 1)
To write the fraction 4 and 1/5 as a percentage, we need to convert it to a decimal first. 1/5 as a decimal is 0.2. Then, add it to the whole number 4 to get 4.2. Finally, multiply 4.2 by 100 to get the percentage, which is 420%.
Roman ' D ' = 500.For a number over 500, write ' D ', then follow it with the amount over 500.For example:To write 511, (recalling that ' X ' = 10, and ' I ' = 1),D X I
500/10000 = 1/20 in its simplest form
420 million can be written as 420,000,000 in digits.
You can write a simple equation: x + (x+1) = 420, where x is the first number. Alternatively, you can make x the second number and write x + (x - 1) = 420. Using the first one, x + x + 1 = 420, so 2x + 1 = 420. 2x = 419 (subtract 1), so x = 209.5. You can check this answer: 209.5 + 210.5 = 420.
500 + 420 + 669944 + 154104 = 824968
