Answer 1

Answer:

based on which one do you want

Step-by-step explanation:

Totals up to=7.425

Rounding off to the nearest hundredth=7.43

Rounding off to the nearest tenth=7.4

Rounding off to the nearest whole number=7

Answer 2

To find:

Round off the solution: 2.545 + 1.780 + 3.1

Step-by-step explanation:

First we find the solution and then find the round-off values.

Now, 2.545 + 1.780 + 3.1

= 7.425

Before we round-off, we must know that the first place after the decimal point is called tenths place, then hundredths place and then thousandths place.

Since the thousandths digit it 5 and the hundredths digit is 2, we can add 1 with 2, that is, the number becomes 7.43 when rounded off to the hundredths place.

Now when 7.43 is to be rounded off to the tenths place, we will not add anything with 4 because 3 < 5. So the rounded off number be 7.4.

Similarly when rounded off as a whole number, it will be 7.

Final answer:

1. Sum = 7.425
2. Round-off (hundredths place) = 7.43
3. Round-off (tenths place) = 7.4
4. Round-off (whole number) = 7
