Which numbers round to 7.91 when rounded to the nearest hundredth? Select all that apply.
DENIUS [597]
Answer:
A, D and E.
Step-by-step explanation:
We're going to examine the thousandth digit to answer this question.
In the case of A, the thousandth digit is 4, therefore we can round it down to zero, this results in 7.910 which is 7.91.
In the case of 7.905, we do the same with the digit 5, this will gives us 7.90.
For C, we can round down the digit 1 to zero, this will give us 7.90.
For D, we take the 5 and round it down to zero and this gives us 7.91.
For E, we take the 9 from the thousandths and we will round it up, therefore the .709 transforms into .710, this gives us 7.91.

Which statements are true about the decimal 0.4 and 0.06
forsale [732]

None of the statements seem to be true. Essentially, the following should be true

0.4>0.06 because 4/10 > 6/100

0.4 > 0.06 because 4 tenths is greater than 6 hundredths

Step-by-step explanation:

To decide which decimal number is bigger, we first check the whole numbers (on the left of the decimal point). If the whole numbers are similar we move to the tenths number (on the right of the decimal point)

We compare the tenths numbers. Whichever has the greatest number is the greater of th two decimal numbers.

If the tenths numbers are similar, we move to the hundredths. The one with the largest number is the greater of the two.

If they are similar we move to the thousandths number and so on...

until we can resolve the two numbers
