Texas Go Math Grade 5 Lesson 2.2 Answer Key Multiply by 2-Digit Numbers

Refer to our Texas Go Math Grade 5 Answer Key Pdf to score good marks in the exams. Test yourself by practicing the problems from Texas Go Math Grade 5 Lesson 2.2 Answer Key Multiply by 2-Digit Numbers.

Unlock the Problem

A Siberian tiger sleeps as much as 18 hours a day, or 126 hours per week. About how many hours does a tiger sleep in a year? There are 52 weeks in one year.

Use place value and regrouping

STEP 1: Estimate: 126 × 52 Think: 100 × 50 = 5,000

Use patterns of zeros to find the product of multiples of 10. 3 × 4 = 12 3 × 40 = 120 30 × 40 = 1,200 3 × 400 = 1,200 300 × 40 = 12,000 So, A Siberian tiger sleeps about 6,552 hours in one year.

Are there different numbers you could have used in Step 1 to find an estimate that is closer to the actual answer? Explain. Answer: From the above Problem, We can observe that Step 1: Estimate: 100 × 50 Now, The actual numbers are: 126 × 52 So, The different sets of numbers that can also be used to find the Estimate are: 125 × 50 = 6,250 Hence, from the above, We can conclude that Yes, we can use the different sets of numbers to find an estimate that is closer to the actual answer

Problem Solving

Practice: Copy and Solve Estimate. Then find the product.

Question 14. When you multiply 235 and 4 tens in 235 × 43, why does its product have a zero in the one’s place? Explain. Answer: It is given that You multiply 235 and 4 tens in 235 × 43 Now, In 235 × 43, The partial products are: 235 × 3 and 235 × 40 So, In 235 × 40, We can write 235 × 40 as 235 × 4 × 10 Since, We are multiplying 235 × 4 with 10, the product will have the last digit as zero

Go Math Lesson 2.2 5th Grade Answer Key Question 15. Write Math Communicate How is multiplying a number by a 2-digit number similar to multiplying a number by a 1-digit number? How is it different? Answer: Line the numbers up by place value. Example: Regroup 12 into 1 ten and 2 ones. Add the 1 ten you regrouped. Because the 2 represents tens, the numbers will start in the tens column. Now, Step One: Line Up All the Digits. First, line up all of the numbers according to their place value. Step Two: Multiply by the One’s Digit. Step Three: Add a Zero Place Holder. Step Four: Multiply by the Tens Digit. Step Five: Add the Two Answer Rows Together.

Eureka Math Grade 5 Module 6 Lesson 5 Answer Key

Engage ny eureka math 5th grade module 6 lesson 5 answer key, eureka math grade 5 module 6 lesson 5 problem set answer key.

Question 3. For each pair of points below, think about the line that joins them. For which pairs is the line parallel to the x-axis? Circle your answer(s). Without plotting them, explain how you know. a. (1.4, 2.2) and (4.1, 2.4) b. (3, 9) and (8, 9) c. (1\(\frac{1}{4}\), 2) and (1\(\frac{1}{4}\), 8) Answer: Option b Explanation : To form a parallel line to x -axis, the y-coordinates should be same for all x-coordinates. so in option c we have same y -coordinates b. (3, 9) and (8, 9).

Question 4. For each pair of points below, think about the line that joins them. For which pairs is the line parallel to the y-axis? Circle your answer(s). Then, give 2 other coordinate pairs that would also fall on this line. a. (4, 12) and (6, 12) b. (\(\frac{3}{5}\), 2\(\frac{3}{5}\)) and (\(\frac{1}{5}\), 3 \(\frac{1}{5}\)) c. (0.8, 1.9) and (0.8, 2.3) Answer: Option c Explanation : To form a parallel line to y -axis, the x-coordinates should be same for all y-coordinates. so in option a we have same y -coordinates (0.8, 1.9) and (0.8, 2.3) The 2 Other coordinate pairs that would also fall on this line are (0.8, 2) and (0.8, 2.1)

Question 5. Write the coordinate pairs of 3 points that can be connected to construct a line that is 5\(\frac{1}{2}\) units to the right of and parallel to the y-axis. a. ________________ b. ________________ c. ________________ Answer: A (5\(\frac{1}{2}\) ,\(\frac{1}{2}\)) B (5\(\frac{1}{2}\), 2\(\frac{1}{2}\)) C (5\(\frac{1}{2}\), 3) Explanation : To form a parallel line to y -axis, the x-coordinates should be same for all y-coordinates.

Question 6. Write the coordinate pairs of 3 points that lie on the x-axis. a. ________________ b. ________________ c. ________________ Answer: A ( 3, 0 ) B ( 5, 0) C ( 7, 0) Explanation : To lie 3 points on x – axis y coordinates should be 0 . then any point with different x-coordinates lie on x-axis.
