Step-by-step explanation:
Locate the digit to the right of the place you're rounding to. If that digit is 5 or more, add 1 to the digit in the place you're rounding to. Drop all digits to the right of the one you're rounding to, unless it is left of the decimal point. In that case, zero any digits between the one you rounded and the decimal point. (See problem 3 for an example of this.)
If you're rounding to the ones place (nearest whole number), and that digit ends up being 0, then put a decimal point after it to indicate it is a significant digit.
The second attachment shows the names of the number places, if you need a reminder.
Answer:
The width of the new phone will be of 4.37 inches.
Step-by-step explanation:
This question is solved by proportions, using a rule of three.
In this question:
Length was of 2.2 inches, after the modification is of 2.09 inches.
Width was of 4.6 inches, after the modification is x. So
2.2 - 2.09
4.6 - x
Applying cross multiplication:
The width of the new phone will be of 4.37 inches.
