Answer 1

Answer:

1/3

Step-by-step explanation:

let the number be x

Then, according to question,

(x)*(3/2) - (3/4) = (5/4)

3x/2 = 5/4 - 3/4 = 2/4 = 1/2

3x/2 = 1/2

x = 1/3

Answer 2

$\huge {\red {\mathfrak{Question :-}}}$

• A number multiplied by $\dfrac {3}{2}$ and then decreased by $\dfrac {3}{4}$ gives $\dfrac {5}{4}$. Find the number.

$\huge {\pink {\mathfrak{Solution:-}}}$

Let the required number be x.

Atq,

$\implies (x \times \dfrac{3}{2} ) - \dfrac{3}{4} = \dfrac{5}{4} \\ \\ \implies \dfrac{3x}{2} - \dfrac{3}{4} = \dfrac{5}{4} \\ \\ \implies \dfrac{3x}{2} = \dfrac{5}{4} + \dfrac{3}{4} \\ \\ \implies \dfrac{3x}{2} = \dfrac{5 + 3}{4} \\ \\\implies \dfrac{3x}{2} = \dfrac{8}{4} \\ \\ \implies 3x \times 4 = 2 \times 8 \\ \\ \implies 12x = 16 \\ \\ \implies x = \dfrac{16}{12} \\ \\ \implies x = \dfrac{4}{3}$
