To convert the mixed number 253 into a decimal, we will follow these steps:
- Step 1: Express 53 with a denominator of 10. To do this, multiply both the numerator and the denominator by 2, which gives us: 5×23×2=106.
- Step 2: Convert 106 to a decimal. Since 106 corresponds to 0.6 as a decimal, we can now express it in decimal form.
- Step 3: Add the whole number portion. We already have the whole number 2 from the mixed number, so combining it with 0.6, we have 2.6.
Thus, the decimal representation of 253 is 2.6.
