Texas Go Math Grade 6 Module 4 Are You Ready? Answer Key
Write the decimals represented by the shaded square.
Question 1.
Answer:
We have that 10 squares are 10 of 100 equal parts, or \(\frac{10}{100}\) or 0.1.
Here we have 70 shaded squares, so, they represent 7 × 0.1, or 0.7.
Question 2.
Answer:
We have that 10 squares are 10 of 100 equal parts, or \(\frac{10}{100}\) or 0.1.
Here we have 70 shaded squares, so, they represent 4 × 0.1, or 0.4.
Question 3.
Answer:
We have that 1 square is 1 of 100 equal parts, or \(\frac{1}{100}\), or 0.01.
Also, 10 squares are 10 of 100 equal parts, or \(\frac{10}{100}\), or 0.1.
Here we have 53 shaded squares, we can rewrite them as 503.
So, 3 squares represent 3 × 0.01, or 0.03 and 50 squares represent 50 × 0.1, or 0.5.
Finally, 53 squares represent 0.03 + 0.5 = 0.53
Question 4.
Answer:
Here, we have 100 shaded squares, they are 100 of 100 equal parts, or \(\frac{100}{100}\), or 1.
Find the product.
Question 5.
0.49 × 10 ___________
Answer:
Number of zeros in 10 is 1, so, we have to move the decimal point 1 place to the right and we get that the result is 4.9.
Question 6.
25.34 × 1,000 ___________
Answer:
Number of zeros in 1000 is 3, so, we have to move the decimal point 3 places to the right and we get that the result is 25, 340
Here, because we had two decimal places, we added 0 at the third place because we moved decimal point 3 places.
Question 7.
87 × 100 ___________
Answer:
Here, the number of zeros in 100 is 2. In this case we will add two zeros to 87 and get that the result is 8,700
Write a numerical expression for the word expression.
Question 8.
20 decreased by 8 _______________
Answer:
Decreased means “to subtract 8 from 20”, so, required numerical expression would be 20 – 8.
Question 9.
the quotient of 14 and 7 _______
Answer:
The quotient means the answer in division problem, so, required numerical expression would be \(\frac{14}{7}\)
Question 10.
the difference between 72 and 16 _________
Answer:
The difference between two numbers means to subtract them, so, required expression would be 72 – 16.
Question 11.
the sum of 19 and 3 __________
Answer:
The sum of two numbers means to add them, so, required expression would be 19 + 3.
