Answer:

15 times as much as 1 fifth of 12 is  36

Step-by-step explanation:

Given the statement: 15 times as much as 1 fifth of 12

or we can write this as:

15 times as much as 1/5 of 12

''of '' means multiply

"1/5 of 12" means  [tex]\frac{1}{5} \times 12[/tex]

"times" means [tex]\times[/tex]

then;

[tex]15 \times (\frac{1}{5} \times 12)[/tex]

⇒[tex]15 \times \frac{12}{5}[/tex]

⇒[tex]3 \times 12 = 36[/tex]

Therefore,  15 times as much as 1 fifth of 12 is 36

Further explanation

The Problem:  

  • 15 times as much as 1 fifth of 12.
  • Write an expression to match, and then evaluate.

The Process:

Here are some early expressions that need attention.

  • 1 fifth is [tex]\boxed{\frac{1}{5}}[/tex]
  • 1 fifth of 12 is [tex]\boxed{\frac{1}{5} \times 12}[/tex]

Let us write an expression to match for 15 times as much as 1 fifth of 12.

[tex]\boxed{\boxed{ \ 15 \times \bigg(\frac{1}{5} \times 12 \bigg) \ }}[/tex]

And now we evaluate the expression.

[tex]\boxed{ \ = 15 \times \bigg(\frac{1}{5} \times 12 \bigg) \ }[/tex]

[tex]\boxed{ \ = 15 \times \frac{12}{5} \ }[/tex]

We cross out 15 and 5 because they both can be divided.

[tex]\boxed{ \ = 3 \times \frac{12}{1} \ }[/tex]

[tex]\boxed{ \ = 3 \times 12 \ }[/tex]

[tex]\boxed{\boxed{ \ 36 \ }}[/tex]

Thus, the result is 36.
