Answer 1

SolutioN :

• Just plug in the values of c & d in the given expression and calculate :

`\longrightarrow \bf \: (1)/(4) * 6 + 3 * 7`

`\longrightarrow \boxed{\bf{ (45)/(2) }}`

• Our final answer is 45/2 .

Replace c with 6, and d with 7:-

`\Large\text{$\displaystyle(1)/(4) (6)+3(7)$}`

`\bigstar` On simplification,

`\Large\text{$\displaystyle(1)/(4) *(6)/(1)+21$}`

`\bigstar` On further simplification,

`\Large\text{$\displaystyle(6)/(4) +21$}`

`\bigstar` On further simplification,

`\Large\text{$\displaystyle(6)/(4)+(84)/(4)$}`

`\bigstar` Adding the numerators,

`\Large\text{$\displaystyle(90)/(4)$}`

`\bigstar` Finally, Reducing the fraction:-

`\Large\text{$\displaystyle(45)/(2)$}`
