12/5×15
12×15=180
180/5=36
the is 36

Answer 2

15 × ( ¹/₅ × 12 ) = 36

Further explanation

Order of Operations in Mathematics follow this following rule :

• Parentheses

• Exponents

• Multiplication and Division

• Addition and Subtraction

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
