Rounding your answer to the nearest hundredth in division
4.2/9? ?

Rounding your answer to the nearest hundredth in division of 4.2/9 is 0.47

Solution:

By Simple division when we divide 4.2 ÷9 we get  0.4666667

Now let us round off to nearest hundredth

Rounding off:

Rounding off to nearest hundredth means rounding off to two decimal points

The rounding off rules are:

Here 0.4666667 , the nearest hundred digit is "6"

The digit after "6" is greater than 5. Hence nearest hundredth digit "6" is incremented and becomes "7"

On rounding off we get 0.4666667 = 0.47

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
