so number one is y*y*y*y*y

Round 503.782 to the nearest tenth.

Answers

Answer:

503.8

Step-by-step explanation:

Since the hundredths place is above 4, you round up.

Answer:

503.8

Step-by-step explanation:

Note the tenth place value.

5 (hundreds place value)

0 (tens place value)

3 (ones place value)

.

7 (tenths place value)

8 (hundredths place value)

2 (thousandths place value)

You are trying to solve for the tenths place value. In this case, locate the tenths place value. The value is a 7. Now look at the place value directly next to it (hundredths place value). It is a 8. Because 8 is greater than 4, round up.

503.782 rounded to the nearest tenths is 503.8

Note:

Note the rules of rounding. IF:

The number is 4 or less, round down.

The number is 5 or greater, round up.
