write each mixed number as a decimal.3 and seven tenths. 4 and one half how??
3 and 7/10 is 3.7
4 and 1/2 is 4.5
3.7
4 1/2 = 5/10 = 4.5
To write a mixed number as a decimal, you need to convert the whole number and the fraction separately into decimal form, and then add them together.
Let's start with the first mixed number:
3 and seven tenths.
To convert the whole number "3" into decimal form, you simply write it as it is: 3.
Next, we need to convert the fraction "seven tenths" into decimal form. We can do this by dividing the numerator (7) by the denominator (10).
7 ÷ 10 = 0.7
Now, we add the decimal form of the whole number and the fraction together:
3 + 0.7 = 3.7
Therefore, the decimal form of 3 and seven tenths is 3.7.
Now, let's move on to the second mixed number:
4 and one half.
Again, we start by converting the whole number "4" into decimal form: 4.
Next, we convert the fraction "one half" into decimal form. For a fraction with 1 as the numerator, we divide 1 by the denominator (2).
1 ÷ 2 = 0.5
Now, we add the decimal form of the whole number and the fraction:
4 + 0.5 = 4.5
Therefore, the decimal form of 4 and one half is 4.5.
