Fractions are integers or numbers that have a numerator and a denominator.
To solve the above question, we would be applying the use of fractions.
It will take Molly 12 hours to type the story on her own.
Let's represent:
Total hours it will take both of them to type together = T = 4
Total hours Chole can take to type on her own = C = 6
Total hours it will take for Molly to type on her own = M
Our Formula is given as:
1/T = 1/C + 1/M
Hence:
1/4 = 1/6 + 1/M
Subtract 1/6 from both sides
1/M = 1/4 - 1/6
Lowest common denominator (4, 6) = 12
Hence,
1/M = 3 - 2 / 12
1/M = 1/12
Cross Multiply
M x 1 = 12 x 1
M = 12 hours
Therefore, it will take Molly 12 hours to type the story on her own.
