15 × ( ¹/₅ × 12 ) = 36
Further explanation
Order of Operations in Mathematics follow this following rule :
- Multiplication and Division
This rule is known as the PEMDAS method.
In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.
Let us tackle the problem!
1 fifth of 12
\(\frac{1}{5} \times 12\)
15 times as much as 1 fifth of 12
\(15 \times (\frac{1}{5} \times 12)\)
Let's solve the above operations!
\(15 \times (\frac{1}{5} \times 12) = 15 \times (\frac{1 \times 12}{5})\)
\(15 \times (\frac{1}{5} \times 12) = 15 \times (\frac{12}{5})\)
\(15 \times (\frac{1}{5} \times 12) = \frac{15 \times 12}{5}\)
\(15 \times (\frac{1}{5} \times 12) = \frac{180}{5}\)
\(15 \times (\frac{1}{5} \times 12) = \boxed {36}\)
Conclusion:
15 times as much as 1 fifth of 12 → 15 × ( ¹/₅ × 12 ) = 36
