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.

How do you write 107000523094 in word form?

107,000,523,094Start on the left and work towards the right:The first three digits are "one hundred and seven billion",then you skip over the zeroes, and find "five hundred and twenty-three thousand",and finally "ninety-four".So, "one hundred and seven billion, five hundred and twenty-three thousand, ninety-four".


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 write seventeen eighths as a decimal?

8 goes into 17 twice with one eighth remaining. Then you have to get an eighths value by dividing 1 by 8. You then get .125 so your answer is 2.125. An easier process might be to find the value of one eighth (1 divided by bottom number 8) which is .125 then multiply it by the top number 17. Seventeen eighths equals 2.125 this will work with all fractions.
