Write two different pairs of decimals whose sums are 14.1 and one pair should involve regrouping

The required pair is 8.4 and 5.7

Step-by-step explanation:

Consider the provided information.

It is given that we need to find two  different pairs of decimals whose sums are 14.1 and one pair should involve regrouping

Regrouping: Regrouping is know as borrowing or carrying numbers in order to add or subtract the provided numbers.

It is given that one pair should involve regrouping

Let us take the number are:

8.4 and 5.7

Now add them as shown:

 8.4

+5.7

First start with the right most digits which is 4 and 7 add them 4+7=11, 11 is a two digit number, so bring 1 down and carry 1. Now 8+5 = 13 now add the digit 1 as we carry it, which gives us = 13 + 1 = 14

 8.4

+5.7

14.1

Thus, the answer is 14.1

Hence, the required pair is 8.4 and 5.7

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
