Question

1. 5 less than half of a number is 45.5, find the number.​

Answer 1

Answer:

5 less than half of a number is 45.5=

5-45.5 =45.0

Answer 2

As per the data given in the question,

We have to determine the value of the number.

As per question,

It is given that,

5 less than half of a number is 45.5

So, let the number be "x".

Half of number will be $\frac{1}{2} \times x = \frac{x}{2} = 0.5x$

So, from above we can rewrite the above expression as,

$0.5x - 5 = 45.5$

Now for solving the expression,

We will shift -5 from LHS to RHS,

We will get it as,

$0.5x-5 = 45.5\\=>0.5x = 45.5+5\\=>0.5x = 50.5\\=>x = \frac{50.5}{0.5} = 101$

Hence, value of the given number will be 101.
