SOLUTION

TO DETERMINE

78.5 rounded to one significant figure

CONCEPT TO BE IMPLEMENTED

Rule for rounding off a number :

Discard all digits to the right of the nth place , if the discarded number is less than half a unit in the nth place , leave the nth digit unchanged ; if the discarded number is greater than half a unit in the nth place , add 1 to the nth digit .

If the discarded digit is exactly half an unit in nth digit leaving the nth digit unaltered if it is an even number but increase it by 1 if it is an odd number

EVALUATION

Here the given number is 78.5

We have to round off to one significant figures

1st significant figure = 7

2nd significant figure = 8

8 is greater than half of a unit

So we add 1 with the 1st significant figure

Hence the required number = 80
