To convert the mixed number 1 12 into a decimal, we first need to understand its components. The mixed number consists of a whole number (1) and a fraction (12). The fraction is understood to be 12/1, which is simply 12.
Now, we can convert the whole number and the fraction separately. The whole number 1 is already in decimal form, which is 1.0. For the fraction 12, since it’s essentially the whole number itself in this case, it can be expressed as 12.0 in decimal form.
Finally, we combine these two parts together: 1 (the whole) + 12 (the fraction). Therefore, 1 12 as a decimal is 13.0.
