Question

The product of two decimals is 0.238.if one of them is 1.4, find the other.
​

Answer 1

Answer:

The other number is 0.17.

Step-by-step explanation:

Given,

The product of two decimals is 0.238 and one of them is 1.4.

To find,

The other number.

Solution,

Let us assume that $x$ is the other number.

As it is given that, the product of two decimals is 0.238 and one of them is 1.4. Therefore,

$\begin{array}{l} \Rightarrow 1.4 \times x = 0.238 \\ \Rightarrow 1.4x = 0.238 \\ \Rightarrow x = \frac{0.238}{1.4} \\ \Rightarrow x = 0.17\end{array}$

Hence, the other number is 0.17.

Answer 2

Question

$\leadsto$ The product of two decimals is 0.238.if one of them is 1.4, find the other.

Answer -1

Given : -

• The product of two decimals is 0.238 and if one of them is 1.4.

To Find : -

• The other decimal

Solution : -

We have ,

• Product of two decimals

=> 0.238

• One decimal => 1.4

$\implies \sf\bold{\purple{ \therefore The \: other \: decimal =}}$

$\mapsto \sf \ \frac{0.238}{1.4}$

$\mapsto \sf \frac{0.238 \times 100}{1.4 \times 100}$

$\mapsto \sf \frac{23.8}{140}$

$\mapsto \sf \ \frac{0.238}{1.4}$

$\implies \bf\bold{\pink{(0.17)}}$

Hence ,

• The other decimal is 0.17 .

Answer -2

Consider : -

Let's consider the x and y be the two decimals .

Given : -

• The product of two decimals = 0.238
• ∴ x × y = xy = 0.238

• The product of one of the decimal = 1.4
• ∴ x = 1.4

To Find : -

• Value of other decimal that is value of y

Solution : -

$\mapsto \sf \ \: \therefore x \times y = 0.238$

• Put the value of x in this ,

we get

$\mapsto \sf \ \: \therefore 1.4 \times y = 0.238$

$\mapsto \sf \ \: \therefore y = \frac{0.238}{1.4}$

$\implies \bf\bold{\pink{(0.17)}}$

Hence,

The other decimal is y = 0.17
