Where on a ruler is 7 and 3 eighths?

go to the 7 then count 6 of the little lines. 6/16ths Here is an alternate method that will work if your ruler happens not to mark 16ths. Make sure that you are using a ruler that measures inches and feet. A stick that measures in the metric system will not work well. 7 3/8 will be between the 7 inch and the 8 inch points. The "eighths" part means that you are looking for the marks that divide that inch into eight equal lengths. There will be 3 such marks or lines in between the 7 and the half inch mark which you should be able to find with no trouble. There are three more 'eighths' marks between the half inch mark and the 8. The "3" part means that you start at the 7 point on the ruler and count three of the marks that divide the inch into eighths. You will also see (or you are making an error of some kind) that if you count 4 eighths from the 7 point, you will be exactly at the half inch mark between the 7 and the 8. That only makes sense; 4 eighths is half of 8 eighths. And 8 eighths is one full unit-- in this case, one full inch.


What does 14 equals how many eighths?

Oh, dude, 14 is the same as 112 eighths. You just gotta multiply 14 by 8 to get that answer. So, like, if you ever need to split 14 into eighths, you've got 112 pieces to work with. Easy peasy!


Seven eighths inches divided by two?

7/8 x 1/2 is your question. To work it you multiply your tops and you multiply your bottoms. 7 x 1 = 7 and 8 x 2 = 16 so your answer is: 7/16 inches


How many twelfths are in one half?

There are 24 halves in 12, so there must be 1/24 twelves in 1/21/24 = 0.04166Another Take:I may be misunderstanding the question. The above doesn't seem to work too well either. The question originally read: How many twelves are in one half? This did not seem to me to make sense so I changed it to: How many twelfths are in one half? I have noticed that students sometimes will not make a distinction between twelves and twelfths, five and fifths and so forth.The question is How many twelfths (or twelves) are in one half, and not how many halves are in 12. So I conclude that the questioner wants to know that 6 twelfths is equal to half.


How do you show your work for two fifths plus three tenths?

Multiply two fifths by two to get a common denominator. Then you will have 4 tenths plus three tenths. then add straight across and you will get seven tenths.
