question

Read the story.

Louis was doing a science project on unusual bats. The 2 types he picked to study were the bumblebee bat and the giant golden-crowned flying fox. He found 14 interesting facts about the bats in all, and he found the same number of facts for each type. How many facts did Louis find for each type of bat?

Pick the diagram that models the story. Let f represent how many facts Louis found for each type of bat.

Write a multiplication equation with f that models the story.

Equation:

Now, solve for

solution

Start by listing the information given in the problem:

Louis picked 2 types of bats.
He found f facts about each type.
He found 14 facts in all.

This diagram models the story.

facts in all

f facts for each of 2 types

Now, write a multiplication equation that models the story.

2	⋅	f	=	14

number of types		facts for each type		facts in all

To solve for

you can write a related division equation.

Divide to solve for

So, Louis found 7 facts for each type of bat.
