Question

2/5÷ -5/7



solution of the question​

Answer 1

Answer:

→ -14/25

Step-by-step explanation:

Question :

$\sf \longrightarrow \dfrac{2}{5} \div \dfrac{ - 5}{ \: 7}$

Solution :

$\sf \longrightarrow \dfrac{2}{5} \div \dfrac{ - 5}{ \: 7}$

We know :

$\bf \longrightarrow \dfrac{a}{b} \div \dfrac{ m}{n} = \dfrac{a}{b} \times \dfrac{ n}{m}$

Using this :

$\sf \longrightarrow \dfrac{2}{5} \times \dfrac{ \: 7}{ - 5}$

We can see that we can't simplify/cancel anything so we will directly multiply.

$\sf \longrightarrow \dfrac{2 \times 7}{5 \times - 5}$

$\sf \longrightarrow \dfrac{ \: \: \: 14}{ - 25}$

Or,

$\green{ \sf \longrightarrow \boxed{ \bf - \dfrac{14}{ 25} } \: \bigstar}$

Answer 2

• We have to evaluate the above expression by using the given data.

             Given data:- $\frac{2}{5} \div\frac{-5}{7} .$

             To find:- Value of the expression.

             Solution:-

• Follow the steps to solve the above equation.

• Leave the first fraction alone.

• Now change the division sign into multiplication.

• Flip the second fraction.

• Now multiply the numerators.

• similarly, multiply denominators.

• simplify.

        Therefore,

          $\frac{2}{5} \div\frac{-5}{7} \\=>\frac{2}{5} \times\frac{7}{-5} \\=>-\frac{14}{25} \\=>-0.56.$

      Hence we will get the value is $-\frac{14}{25}$ or $-0.56.$
