Neither of your options are correct, it should be seven eights (not eighths) are fifty four.
5.875
Yes, seven eighths is greater than five tenths. Five tenths, or one half, expressed in eighths would be four eighths. Since seven is greater than four, seven eighths is greater than four eighths (or five tenths). One easy way to know is use a calculator and do the division (seven divided by eight, and five divided by ten); in decimal form the higher value may be more quickly apparent when compared.
Seven eighths of a cup is slightly less than one cup. In decimal form, it is .875 cup. That's really the only other way of saying it.
It is: (3/4+7/8)/2 = 13/16
The easiest way is their decimal equivalents. 7/8 = 0.875 5/6 = 0.833 repeating
9/16=0.5625 7/8=0.875 7/8 - 9/16=0.3125 Another way to look at this is to consider that seven eighths is the same as fourteen sixteenths, and fourteen sixteenths is five sixteenths greater than nine sixteenths.
Another way to write one and one eighths is nine eighths.(9/8)
Maybe you need to put your brain into gear of you can't add 2 to 5. The answer's 7 eighths, by the way.
Oh, dude, math time! So, there are 16 sixteenths in a whole, right? And we want to know how many 8 eighths are in 5 sixteenths. Well, 5 sixteenths is like 10 eighths, because you double the number of eighths to get the equivalent in sixteenths. So, there are 10 eighths in 5 sixteenths. Math is fun, right?
You say: "seven to the fourth power." (2401 by the way)
the way you say it is zero and one hundred fifty seven thousandths.
