Question 1.
Use any method to find the greatest common factor for the number pairs.
a. GCF (42, 56) = ___
b. GCF (32, 80) = ___
c. GCF (72, 16) = ___
d. GCF (10, 40, 25) = ____

Answer:
a. GCF of 42 and 56 = 14.
b. GCF of 32 and 80 = 16.
c. GCF of 72 and 16 = 8.
d. GCF of 10, 40, and 25 = 5.

Explanation:
In the above-given question,
given that,
Use any method to find the greatest common factor for the number pairs.
GCF = Greatest Common Factor.
a. GCF of 42 and 56 = 14.
factors of 42 = 1, 2, 3, 6, 7, 14, 21, and 42.
factors of 56 = 1, 2, 4, 7, 8, 14, 28, and 56.
so among those the greatest common factor is 14.
b. GCF of 32 and 80 = 16.
factors of 32 = 1, 2, 4, 8, 16, and 32.
factors of 80 = 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80.
so among those the greatest common factor is 16.
c. GCF of 72 and 16 = 8.
factors of 72 = 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.
factors of 16 = 1, 2, 4, 8, and 16.
so among those the greatest common factor is 8.
d. GCF of 10, 40, and 25 = 5.
factors of 10 = 1, 2, 5, and 10.
factors of 40 = 1, 2, 4, 5, 8, 10, 20, and 40.
factors of 25 = 1, 5, and 25.
so among those the greatest common factor is 5.

Question 2.
Explain how you found GCF (42, 56) in Problem 1a.

Answer:
GCF of 42 and 56 = 14.

Explanation:
In the above-given question,
given that,
GCF = Greatest Common Factor.
GCF of 42 and 56 = 14.
factors of 42 = 1, 2, 3, 6, 7, 14, 21, and 42.
factors of 56 = 1, 2, 4, 7, 8, 14, 28, and 56.
so among those, the greatest common factor is 14.

Question 3.
Use the GCF to find an equivalent fraction for \(\frac{48}{64}\). Show your work.

Answer:
48/64 = 3/4.

Explanation:
In the above-given question,
given that,
use the GCF to find an equivalent fraction for 48/64.
48 = 6 x 8.
64 = 8 x 8.
6/8 = 3/4.
6 = 2 x 3.
8 = 2 x 4.
so 48/64 = 6/8.

Question 4.
Jenny will use 28 blue beads and 21 red beads to make identical bracelets.
a. What is the greatest number of bracelets she can make?

Answer:
The greatest number of bracelets she can make = 7.

Explanation:
In the above-given question,
given that,
Jenny will use 28 blue beads and 21 red beads to make identical bracelets.
factors of 28 = 1, 2, 4, 7, 14, and 28.
factors of 21 = 1, 3, 7, and 21.
so among those, the greatest common factor = 7.

b. How many blue beads and how many red beads will be on each bracelet?

Answer:
The number of blue beads and red beads will be on each bracelet = 7.

Explanation:
In the above-given question,
given that,
the number of blue beads = 4.
the number of red beads = 3.
4 + 3 = 7.
so the number of blue beads and red beads will be on each bracelet = 7.

Question 6.
GCF (12, 24, 30, 42) =

Answer:
GCF of 12, 24, 30, and 42= 6.

Explanation:
In the above-given question,
given that,
GCF of 12, 24, 30, and 42.
factors of 12 = 1, 2, 3, 4, 6, and 12.
factors of 24 = 1, 2, 3, 4, 6, 8, 12, and 24.
factors of 30 = 1, 2, 3, 5, 6, 10, 15, and 30.
factors of 42 = 1, 2, 3, 6, 7, 14, 21, and 42.
so among those, the greatest common factor = 6.

Answer:
a. LCM of 10 and 15 = 30.
b. LCM of 12 and 15 = 60.
c. LCM of 6 and 10 = 30.
d. LCM of 7 and 5 = 35.

Explanation:
In the above-given question,
given that,
LCM of 10 and 15.
2 x 5 = 10.
3 x 5 = 15.
5 x 1 = 5.
2 x 3 x 5 = 30.
so LCM of 10 and 15 = 30.
LCM of 12 and 15.
12 = 3 x 4.
15 = 3 x 5.
3 x 4 x 5 = 60.
LCM of 6 and 10.
6 = 2 x 3.
10 = 2 x 5.
3 x 1 = 3.
5 = 5 x 1.
2 x 3 x 5 = 30.
LCM of 5 and 7.
5 x 7 = 35.

Question 2.
Find the greatest common factor and least common multiple for each pair of numbers.
a. GCF (75, 100) = ___
LCM (75, 100) =

Answer:
a. GCF of 75 and 100 = 25.
b. LCM of 75 and 100 = 300.

Explanation:
In the above-given question,
given that,
LCM of 75 and 100.
75 = 5 x 15.
100 = 5 x 20.
15 = 5 x 3.
20 = 5 x 4.
5 x 5 x 3 x 4 = 300.
GCF of 75 and 100.
75 = 3 x 5 x 5.
100 = 2 x 2 x 5 x 5.
5 x 5 = 25.

b. GCF (36, 48) = ___
LCM (36, 48) =

Answer:
a. GCF of 36 and 48 = 12.

How many necklaces can she make? Number model: ______ Solution: _________

Answer:
The number of necklaces she can make = 10.

Explanation:
In the above-given question,
given that,
Michelle is cutting string to make necklaces.

Question 4.
A rectangular window has an area of 4\(\frac{1}{2}\) square meters. Its width is \(\frac{3}{4}\) meter. What is its length?
Number model: ____ Solution: ___

Answer:
The length of the rectangular window = 6 m.

Explanation:
In the above-given question,
given that,
A rectangular window has an area of 4 x 1/2 sq m.
4 x 2 = 8.
8 + 1 = 9.
9/2 = 4.5.
width = 3/4.
3/4 = 0.75.
area = l x w.
4.5 = l x 0.75.
l = 4.5/0.75.
length = 6.
so the length of the rectangular window = 6 meters.

The area of a rectangle is 10\(\frac{1}{2}\) square feet. The length is 5\(\frac{1}{4}\) feet. How wide is the rectangle?
Everyday Math Grade 6 Home Link 2.7 Answer Key 35.2
Answer: ____
The width of the rectangle = 2 ft.

Explanation:
In the above-given question,
given that,
the area of a rectangle is 10(1/2) sq ft.
length = 5 (1/4) ft.
10 x 2 = 20.
20 + 1 = 21.
21/2 = 10.5.
5 x 4 = 20.
20 + 1 = 21.
21/4 = 5.25.
area = l x w.
10.5 = 5.25 x w.
w = 10.5/5.25.
w = 2 ft.
so the width of the rectangle = 2 ft.
