Question

8/10-2/6 subtracting fraction with unlike denominators

Answer 1

We have the following general rule for the substraction of fractions:

`\begin{gathered} (a)/(b)-(c)/(d)=(a\cdot d-b\cdot c)/(b\cdot d) \\ b,d\\e0 \end{gathered}`

then, in this case we have the following:

`(8)/(10)-(2)/(6)=(8\cdot6-10\cdot2)/(10\cdot6)=(48-20)/(60)=(28)/(60)`

simplifying, we get:

`(28)/(60)=(7)/(15)`

therefore, the result of the substraction is 7/15
