LCD (1/7, 14/7, 12/13, 5/6)
LCM = (7, 7, 13, 6)
= 2 * 3 * 7 * 13
= 546
1/7 = 78/546
14/7 = 1092/546
12/13 = 504/546
5/6 = 455/546
Calculation:
1/7 + 14/7
= 1 + 14/7
= 15/7
The common denominator you can calculate as the least common multiple of the both denominators: LCM (7, 7) = 7
Add:
15/7 + 12/13
= 15 . 13/7. 13 + 12 . 7/13 . 7
= 195/91 + 84/91
= 195 + 84/91
= 279/91
The common denominator you can calculate as the least common multiple of the both denominators: LCM (7, 13) = 91
Add:
279/91 + 5/6
= 279 . 6/91 . 6 + 5 . 91/6. 91
= 1674/546 + 455/546
= 1674 + 455/546
= 2129/546
The common denominator you can calculate as the least common multiple of the both denominators: LCM (91, 6) = 546
Hence, 546 is the LCM/LCD of (1/7, 14/17, 13/13, 5/6).

Answer:
C. 73 if I have read the given angle measurements correctly.
The angle measurements I see are:
.
Step-by-step explanation:
Those angles together form a full rotation. A full rotation is equal to 360 degrees.
So we have the following equation to solve:
Combine like terms:
Simplify:
Divide both sides be 2:
Subtract 107 on both sides:
Answer:
change the division sign to a multiplication sign then flip the second fraction with the bottom on the top and the top on the bottom then multiply if its a improper fraction make it into a whole fraction
Step-by-step explanation:
Q 2/3 ÷ 3/7
1 change the divison sign
x = ÷
2 then the second fraction flip it
2/3÷7/3
3 then multiply the fraction
2/3 ÷ 7/3= 14/9 or 1 5/9
