272×143=
To solve this problem, we'll follow these steps:
- Convert each mixed number into an improper fraction.
- Multiply the two improper fractions.
- Simplify the resulting fraction if necessary.
- Convert the final product back to a mixed number if desired.
Now, let's work through each step:
Step 1: Convert the mixed numbers into improper fractions.
For 272:
272=72×7+2=714+2=716
For 143:
143=41×4+3=44+3=47
Step 2: Multiply the improper fractions.
716×47=7×416×7=28112
Step 3: Simplify the resulting fraction.
Since 112÷28=4,
28112=4
The final result is a whole number, so there is no need for conversion back to a mixed number.
Therefore, the solution to the problem is 4.
