Further explanation

Given:

• Anna and Belle plan to put together their weekly allowances to be donated to an animal care foundation.
• They have $12 and $8, respectively.
• They agreed to set aside one-fifth of their money.

Question:

Write expressions to match and then solve it.

The Process:

Here are some early expressions that need attention.

• one-fifth is $\boxed{\frac{1}{5}}$
• the sum of 12 and 8 is $\boxed{(12 + 8)}$

The expression for one-fifth of the sum is $\boxed{\frac{1}{5} \times (12 + 8)}$ which is the amount of money they are donating together.

We know that the key word or phrase 'of' is used to describe a common mathematical operation, which is multiplication. It is synonymous with 'the product'.

Here are the steps to solve the expression.

Firstly, we add up their weekly allowances.

$\boxed{ \ \ 12 + \ 8 = \ ? \ }$

$\boxed{\boxed{ \ \ 20 \ }}$

Secondly, one-fifth multiplied by the number of their weekly allowances.

$\boxed{ \ = \frac{1}{5} \times (12 + 8) \ }$

$\boxed{ \ = \frac{1}{5} \times \ 20 \ }$

Or it can be written as, $\boxed{ \ = \ 20 \div 5 \ }$

$\boxed{\boxed{ \ \ 4 \ }}$

Thus, they donated together for $ 4.
