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.

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.

Lesson 6 Ex1

Plan

Solve a simpler problem. First, find one sixth of

a smaller number. Then, multiply to find one

sixth of 420.

Lesson 6 Ex1

Solve

Find one sixth of 42.

Draw 42 circles in 6 equal

rows. Circle one of the six equal groups.

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.

Lesson 6 Ex1

Check

Since 70 6 420, then 70 is one sixth of 420.

The answer is correct.
