Eureka Math Grade 4 Module 2 Lesson 4 Problem Set Answer Key

Question 1. Complete the table.

Explanation: Completed the table as shown above as smaller unit one is 100 times than larger unit hundred, 1 X 100 = hundred, smaller unit centimeter is 100 times than larger unit meter, 1 centimeter X 100 = 1 meter, smaller unit one is 1,000 times than larger unit thousand, 1 X 1,000 = 1 thousand, smaller unit gram is 1,000 times than larger unit kilogram, 1 gram X 1,000 = 1 kilogram, smaller unit meter is 1,000 times than larger unit kilometer, 1 meter X 1,000 = 1 kilometer, smaller unit milliliter is 1,000 times than larger unit liter, 1 milliliter X 1,000 = 1 liter, smaller unit centimeter is 100,000 times than larger unit kilometer, 1 centimeter X 100,000 = 1 kilometer.

Question 2. Fill in the units in word form. a. 429 is 4 hundreds 29 _ones__ b. 429 cm is 4 _meter_ 29 centimeter. c. 2,456 is 2 _thousand_ 456 ones. d. 2,456 m is 2 _kilometer_ 456 meter. e. 13,709 is 13 _thousand_ 709 ones. f. 13,709 g is 13 kilogram 709 _gram_

a. 429 is 4 hundred 29 ones,

Explanation: Units in word form for 429 = 4 X 100 + 29 X 1 = 4 hundred 29 ones,

b. 429 cm is 4 meter 29 centimeter,

Explanation: Units in word form for 429 cm as 1 meter is equal to 100 cm so 4 x 100 cm + 29 cm = 4 meter 29 centimeter.
