Ah, isn't that a happy little question! If a score is 20, then 10 is known as half of that score. Just like how a painting needs balance, numbers need balance too. So, 10 is half of 20, creating a beautiful harmony in our mathematical world.
A "score" is 20. So 3 times 20 plus 10 = 70.
A score is 20. So a century is 5 score.
A "score" is equal to 20 years, so four score would be 4 times 20, which is 80 years. Adding 10 years to that gives a total of 90 years. Therefore, 4 score and 10 equals 90 years.
A "score" is equal to 20 years, so 4 score amounts to 80 years (4 x 20). Adding the 10 years gives a total of 90 years. Therefore, 4 score and 10 equals 90 years.
A score is 20 years. A decade is 10 years. So in 10 decades we've had 100 years. Thus there are 5 scores in 10 decades. 10 Years/1 Decade x 10 Decades ÷ 20 years/1 score = 5 scores
A "score" is 20. So 3 times 20 plus 10 = 70.
A score is twenty; if read as 'a score, ten and three' it is 20 + 10 + 3 = 33, but if read as 'a score [times] ten' it becomes 203.
20 years
A score is 20. So a century is 5 score.
a score is 20 twenty years, so score half means 10 years.
A "score" is equal to 20 years, so four score would be 4 times 20, which is 80 years. Adding 10 years to that gives a total of 90 years. Therefore, 4 score and 10 equals 90 years.
A score is 20. 6 score is 120, so there are 10 dozens.
A score is 20 years. A decade is 10 years. So in 10 decades we've had 100 years. Thus there are 5 scores in 10 decades. 10 Years/1 Decade x 10 Decades ÷ 20 years/1 score = 5 scores
There is no name for 15 other than related to 10 or 20. A decade is 10 years and a score is 20. So, 15 can be 3/4 score or 1.5 decades.
A score is 20, so 200 years would be 10 score years.
Score = 20. So 20 score = 20*20 = 400
A dozen is twelve. A score is twenty. 12 to 20=6/10=3/5
