Question

Five over seven minus one over four?

Answer 1

Answer: thirteen over twenty eight

Step-by-step explanation:

The common denominator you can calculate as the least common multiple of the both denominators - LCM(7, 4) = 28. The fraction result cannot be further simplified by cancelling.

In words - five sevenths minus one quarter = thirteen twenty-eighths.

Answer 2

`(13)/(28)`

Explanation:

Based on how you're phrasing the question, you're asking for the value of
`(5)/(7)-(1)/(4)`

First, figure out the smallest common denominator of 4 and 7.

This would be 28
`((5)/(7)*(28)/(28))-((1)/(4)*(28)/(28))\\\\((5*4)/(28))-((1*7)/(28))\\\\(20)/(28) -(7)/(28) \\\\(20-7)/(28) \\\\(13)/(28) \\`. Therefore, multiply each fraction by
`(14)/(14)`
