Answer 2

Answer:

Therefore, we have round off all the decimals  

a) 80.599 = 80.6

b) 3.841 = 3.84  

c) 5062.98 =  5062.98

d) 85.039 = 85.04

e) 4927.69 = 4928.

Concept:

When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done. The crucial figures are preserved when numbers are rounded off. Simply put, the number of figures that are known with some degree of certainty constitutes the number of important figures in a result.

Given:

We have to round off these decimals a) 8 0.5 9 9 b) 3.8 41 c) 506 2.98

d) 85.039 e) 4 9 27.69 .

Calculation:

a) 80.599 (to the nearest tenths) = 80.6

We have to look at tenth place after decimal point and check whether it is below 5, 5 or above 5.

b)  3.841 (to 2 decimal point) = 3.84

A method to estimate a decimal number's value up to the hundredths place is to round it to two decimal places.

c)  5062.98 (to the nearest hundreds) = 5062.98

Any decimal number is rounded to the nearest hundredth by the term "to the nearest hundredth."

d) 85.039 (to the nearest hundredths) = 85.04

Any decimal number is rounded to the nearest hundredth by the term "to the nearest hundredth."

e)  4927.69 (to the nearest whole number) = 4928

The term "rounding up" refers to rounding numbers up to the nearest whole number bigger than the supplied one. For example, if a number is given in decimal form and is followed by the numbers 5, 6, 7, 8, and 9 after the decimal point.

Hence, we have round off all the decimals  

a) 80.599 = 80.6

b) 3.841 = 3.84  

c) 5062.98 =  5062.98

d) 85.039 = 85.04

e) 4927.69 = 4928.
