Question

Fractions with money.4. $27 ÷ 3/25. 2/5 of $906. $2 ÷ 5/3

Answer 1

`18,36,\: (6)/(5)`

1) When we need to divide fractions all we have to do is to multiply the first one by the reciprocal of the second one.

2) So let's do it, simplifying it whenever possible:

`\begin{gathered} 4)27/(3)/(2)=27*(2)/(3)=18 \\ \end{gathered}`

3) Notice that the preposition "of" denotes a multiplication so we can write out:

`(2)/(5)*90=(180)/(5)=36`

4) And now, let's divide that whole number "2" by 5/3:

`2/(5)/(3)=2*(3)/(5)=(6)/(5)`

5) Thus the answers are:

`18,36,\: (6)/(5)`
