You look to the thousands place and if that number is greater than 5 or 5 you add 1 to thehundreths place, if it is less than 5 than it stays the same. Example 1.3478 1.348
The value of the digit 5 is 5/10. 2.5 = 2+5/10
To find 10% of a number move the decimal point 1 place to the left. Therefore 10% of 2,500,000 would be 250,000.0
Exactly that ... negative exponents. For example: 1000 = 103 That is a positive exponent. .001 = 10-3 That is a negative exponent. For positive exponents, you move the decimal place that many positions to the right, adding zeros as needed. For negative exponents, you move the decimal place that many positions to the LEFT, adding zeros as needed. And, the special case is this: 100 = 1.
There are 5.22055 ounces in 148 grams, since 1 gram = 0.03 oz
round 0.2975 to 1 decimal place = 0.3
2.73 ≈ 2.7 to 1 decimal place
It is then 31.2 when rounded to 1 decimal place
You round to 1.0
6.5- you round it until it has one decimal.
4.96432 rounded to 1 decimal place is 5.0.
It is 4.1 when rounded to 1 decimal place
3.3 rounded to 1 decimal place is 3.0.
Go to the second decimal place; if it is less than 5; round down. If it is 5 or greater, round up. So, 1.51 rounded to 1 decimal place is 1.5.
6.32 rounded to 1 decimal place = 6.3
because
334.4 is already in 1 decimal place
