Question

Plsss help meeee!!!!!!! if your curious what is the (of) (●) its multiplication.​

Answer 1

a) 15/32

b) 1/4

c) 7/12

d) 12/35

Step-by-step explanation:

Here the given sign (•) and (of) are Multiplication sign. So, let us solve this question by multiplication.

a) 3/4 of 5/8

`\begin{gathered} \begin{array}{l}\implies\tt{(3)/(4) \: of \: (5)/(8)} \\ \\\implies\tt{(3)/(4) * (5)/(8)} \\ \\ \implies\tt{(3 * 5)/(4 * 8)} \\ \\ \implies\tt{\underline{\underline{\pink{(15)/(32)}}}} \end{array}\end{gathered}`

• Hence, the answer is 15/32

`\begin{gathered}\end{gathered}`

b) 3/8 • 2/3

`\begin{gathered} \begin{array}{l}\longmapsto\tt{(3)/(8) \bull (2)/(3)} \\ \\\longmapsto\tt{(3)/(8) * (2)/(3)} \\ \\ \longmapsto\tt{\frac{3}{\cancel{8}} * \frac{\cancel{2}}{3}} \\ \\ \longmapsto\tt{\frac{\cancel{3}}{4} * \frac{1}{\cancel{3}}} \\ \\ \longmapsto\tt{(1* 1)/(4 * 1)} \\ \\ \longmapsto\tt{\underline{\underline{\purple{(1)/(4)}}}} \end{array}\end{gathered}`

• Hence, the answer is 1/4.

`\begin{gathered}\end{gathered}`

c) 2/3 of 7/8

`\begin{gathered} \begin{array}{l}\longrightarrow\tt{(2)/(3) \: of \: (7)/(8)} \\ \\\longrightarrow\tt{(2)/(3) * (7)/(8)} \\ \\ \longrightarrow\tt{\frac{\cancel{2}}{3} * \frac{7}{\cancel{8}}} \\ \\ \longrightarrow\tt{(1 * 7)/(3 * 4)} \\ \\ \longrightarrow\tt{\underline{\underline{\blue{(7)/(12)}}}} \end{array}\end{gathered}`

• Hence, the answer is 7/12.

`\begin{gathered}\end{gathered}`

d) 4/5 • 3/7

`\begin{gathered} \begin{array}{l}\dashrightarrow\tt{(4)/(5) \bull(3)/(7)} \\\\\dashrightarrow\tt{(4)/(5) * (3)/(7)} \\\ \\ \dashrightarrow\tt{(4 * 3)/(5 * 7)} \\ \\ \dashrightarrow\tt{\underline{\underline{\red{(12)/(35)}}}} \end{array}\end{gathered}`

• Hence, the answer is 12/35.
