Answer:
1. n = 38
2. n = 22
3. GCF = 2
4. LCM = 36
5. a. x
b. ✓
c. x
d. ✓
e. ✓
f. ✓
Step-by-step explanation:
1. ( 2 + 4 ) x 6 + 4 - 10 ÷ 5 = n
6 x 6 + 4 - 10 ÷ 5 = n
36 + 4 - 2 = n
38 = n
2. 3 x ( 3 + 7 ) - 16 ÷ 2 = n
3 x 10 - 16 ÷ 2 = n
30 - 8 = n
22 = n
3. 20 = 2 x 5
28 = 2 x 2 x 7
GCF = 2
4. 9 = 9 18 27 36 45
12 = 12 24 36 48
LCM = 36
5. a. Improper fraction is a fraction whose numerator is greater than the denominator.
b. Mixed number is a combination of a whole number and a fraction.
c. Similar fractions are fractions with the same denominator.
d. Same with 5. a., Improper fraction is a fraction whose numerator is greater than the denominator.
e. Same with 5. c., Similar fractions are fractions with the same denominator.
f. A Proper fraction is a fraction whose numerator is lower than the denominator.
