Question

is 9 cm 4 mm longer than equal to or shorter than 904 mm​

Answer 1

Answer:

Juliana wants to build a doghouse. She has a few long pieces of wood. Her instructions say that she needs to cut one of the boards in to a piece that is 200 centimeters long, but she only has a meter stick. She wants to figure out if she can measure the entire length using only the meter stick. How can she compare the 200 cm to the meter stick?

In this concept, you will learn how to compare measurements that have different units.Comparing Measurements of Different Units

The word equivalent means equal.

Here is a measurement chart of equivalent measurements.

1 cm1 m1 m1 km=10 mm=100 cm=1000 mm=1000 m

Let’s say that you wanted to compare two different units to figure out which is greater and which is less. You can use the chart to help you.

5 cm ______ 70 mm

The first thing that you need to do is convert the measurements so that the unit of measurement is the same.

You need to have either all mm or all cm. It doesn’t matter which one you choose, as long as it is the same unit. Let’s use cm.

70 mm70÷10=––––––– cm=7

70 mm = 7 cm.

Let’s rewrite the problem.

5 cm ______ 7 cm

Use greater than >, less than < or equal to = to compare the measurements.

5 cm < 7 cm

The answer is 5 cm < 70 mm.

Let's try an example.

7000 m ______ 8 km

Here you have two different units of measurement. You have meters and kilometers.

First, convert both to the same unit. Let’s convert to meters this time.

8 km = 8 × 1000 = 8000 m

Then, compare.

7000 m < 8000 m

The answer is 7000 m is less than 8 km.

Answer 2

Answer:

Solution:

=> 100mm = 1cm

=> 904mm = 9.04cm

● Both are EQUAL.
