To solve the problem of multiplying the whole number 4 by the mixed number , follow these steps:
Thus, the product of and is .
The correct answer is .
\( 5:\frac{2}{5}= \)
Because a mixed number like is one single number, not two separate parts! Think of it like 3.67 - you wouldn't multiply the 3 and .67 separately. Converting to an improper fraction keeps it as one unified value.
Use this formula: Multiply the whole number by the denominator, add the numerator, keep the same denominator. For : (3×3)+2 = 11, so it becomes .
You can use the distributive property: . Both methods work, but the improper fraction method is more reliable!
Divide the numerator by the denominator! For : 44 ÷ 3 = 14 with remainder 2. The quotient (14) becomes the whole number, remainder (2) stays as numerator, denominator (3) stays the same: .
Break it down: Convert → Multiply → Convert back. Practice with easier numbers first, like . Remember, math is about understanding patterns - once you see the pattern, it becomes much easier!
