4 1.The decimal form of 30+8+4divided 100​

Answer 1

Answer:

38.04 this is the answer of this questions

Answer 2

Answer: 0.42

30 + 8 + 4/100

First, we will add the numbers on top

38 + 4/100

42/100

Now we have a fraction. To convert into decimal we have to divide the numerator by the denominator but here since the denominator is 100, there is a special method to do it. this method is suitable for any number in the denominator containing values such as 10, 100, 1000, 10000, etc...First, we have to see how many zeroes it has. In this case, there are 2 zeroes, so we have to remove the 100 and put 2 decimal places to the left of the numerator.  Here the numerator is 42, we can also write it as 42.0, So if we move 2 decimal places to the left, we get 0.42. Therefore the answer is 0.42
