Convert to decimal fraction 45
To solve this problem, we'll follow these steps:
- Step 1: Directly divide the numerator by the denominator.
- Step 2: Perform long division to find the decimal equivalent.
- Step 3: Use equivalent fractions to line up the denominator with a power of 10, like 100.
Now, let's work through each step:
Step 1: The fraction given is 45.
Step 2: Perform the long division:
Divide 5 by 4:
- 4 goes into 5 once, which gives us a whole number of 1. The remainder is 1.
- Bring down a 0 to make 10; 4 goes into 10 twice, giving a decimal value 2 (0.2) and a remainder of 2.
- Bring down another 0 to make 20; 4 goes into 20 exactly 5 times, completing the calculation with no remainder.
This results in a decimal value of 1.25.
Step 3: Convert it to a fraction with a denominator of 100:
- Multiply by 25 to make an equivalent fraction 4×255×25=100125, which directly converts to 1.25 in decimal.
Therefore, the solution to the problem is 1.25.
