Least common denominator of 5/6 and 1/5 is 30
5/6 = 25/30
1/5 = 6/30
It is blank btw. Subject?
So basically the question wants to confuse by saying “6 months” which is half a year, right? Do everything normally until 4yrs and then write into compound interest formula but with n as 1/2 which is root.
Answer:
20 fifths
Explanation:
One rope is 1 m. This can be written as 5/5 meters. One rope will be cut into fifths. Assume that the number of fifths is x, therefore:
x * 1/5 = 5/5
x = 5
This means that each rope will be cut into 5 fifth
Now, for four rope, the number of fifths can be calculated as follows:
number of fifths = 5 * 4 = 20 fifths
Hope this helps :)
