Question

by how much should 74.3 be decreased to get 26.87​

Answer 1

Answer:

Step-by-step explanation:

Let us assume the number be ' x '

74.3 - x = 26.87

-x = 26.87 - 74.3

- x = -47.43

So here minus get cancelled

Therefore x = 47.43

Hence 47.43 must be subtracted from 74.3 to get 26.87

Answer 2

The number by which 74.3 should be decreased to get 26.87, is 47.43.

Given,

Two numbers: 74.3 and 26.87.

To find,

By how much should we decrease 74.3 to get 26.87.

Solution,

Firstly, let's suppose the given number, 74.3 is decreased by x.

So, after decreasing it by x, the result we'll have, is

74.3 - x     ...(1)

Further, it is given that the result we get after decreasing 74.3 by some number (x), is 26.87.

This can be expressed mathematically, using the above expression (1) as follows.

74.3 - x = 26.87

Rearranging and simplifying the above equation, we get,

x = 74.3 - 26.87

⇒ x = 47.43.

Therefore, the number by which 74.3 should be decreased to get 26.87, is 47.43.
