Question

can somebody please help me with my math homework please I really hope the tutors open I've been trying to do this for 5 minutes

Answer 1

The answer is developed in step by step

Explanation:

The first thing is to establish the multiplication and division of fractions

`\begin{gathered} \text{Multiplication} \\ (a)/(b)\cdot(c)/(d)=(a\cdot c)/(b\cdot d) \\ \text{for example} \\ (2)/(3)\cdot(4)/(5)=(2\cdot4)/(3\cdot5)=(8)/(15) \\ \text{Division} \\ (a)/(b)/(c)/(d)=(a\cdot d)/(b\cdot c) \\ \text{for example} \\ (2)/(3)/(4)/(5)=(2\cdot5)/(3\cdot4)=(10)/(12) \end{gathered}`

This means that in the case of multiplication, the numerators multiply each other and the denominators also multiply.

In division, they are also multiplied, but now a cross multiplication is done, multiplying the first numbered by the second denominator and the second numerator by the first denominator.
