4×143=
To solve this mathematical problem, let's follow the outlined approach:
- Step 1: Convert the mixed number to an improper fraction.
- Step 2: Multiply the improper fraction by the whole number.
- Step 3: Simplify the result, if needed.
Let's begin with Step 1 by converting the mixed number 143 to an improper fraction. To do this, multiply the whole number (1) by the denominator (4) of the fraction, and then add the numerator (3):
1×4+3=4+3=7
This gives us the improper fraction 47.
Next, proceed to Step 2: Multiply the whole number, 4, by the improper fraction we found:
4×47=44×7=428
For Step 3, simplify 428:
428=7
Thus, the product of the whole number 4 and the mixed number 143 is 7.
