Lesson 6 Ex1
ANICA My class visited the zoo. I
learned that one sixth of the animals at the zoo
are reptiles. There are 420 animals at the zoo.
How many animals are reptiles? YOUR MISSION
Find how many animals are reptiles.
61
Lesson 6 Ex1
Understand
What facts do you know?

• There are 420 animals at the zoo.
• One sixth of the animals are reptiles.

What do you need to find?

• Find how many animals are reptiles.

62
Lesson 6 Ex1
Plan
Solve a simpler problem. First, find one sixth of
a smaller number. Then, multiply to find one
sixth of 420.
63
Lesson 6 Ex1
Solve
Find one sixth of 42.
Draw 42 circles in 6 equal
rows. Circle one of the six equal groups.
64
Lesson 6 Ex1
Solve
So, one sixth of 42 equals 7. Now multiply.
42 10 420
7 10 70
THINK What number can you multiply 42 by to
equal 420? Then multiply 7 by the same number.
Answer So, 70 of the animals at the zoo are
reptiles.
65
Lesson 6 Ex1
Check
Since 70 6 420, then 70 is one sixth of 420.
The answer is correct.
