How do you do rounding with division?
Solution
- Shifting decimal point one place to the right in both numbers. 9.36 ÷ 6.5 = 93.6 ÷ 65.
- Rounding the quotient to the nearest tenth, we get. 9.36 ÷ 6.5 = 93.6 ÷ 65 = 1.44 ≈ 1.4. Problem – 2. Divide and round to the nearest hundredth. 5.7 ÷ 0.8.
How do you round off a remainder?
Place a decimal point and bring it up to the quotient. Add a 0 onto the remainder, and continue dividing. Add a 0 onto each remainder until the division is exact. If the division will never be exact, round off the quotient to the required number of decimal digits.
How do I make sure my division is correct?
You can use multiplication to check your division answer this way.
- Do the division problem.
- Multiply the quotient times the divisor.
- If there is a remainder, add it to the multiplication product.
- Compare this answer to the dividend. They should be the same number (630 = 630).
Does 5.5 round up or down?
Here’s the general rule for rounding: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.
Does C division round up or down?
When doing an integer division in c++, the result will always be rounded down, so your rounding system isn’t off 🙂 For example even if you divide 1999 by 1000, the result will be 1 if both 1999 and 1000 are integers.
How do you round up decimal places?
There are certain rules to follow when rounding a decimal number. Put simply, if the last digit is less than 5, round the previous digit down. However, if it’s 5 or more than you should round the previous digit up. So, if the number you are about to round is followed by 5, 6, 7, 8, 9 round the number up.
What thousandths look like?
The third decimal digit from the decimal point is the thousandths digit. For example, 0.008 is eight thousandths. Read the whole set of three decimal digits as a number, and say “thousandths.” 0.825 has 8 tenths, 2 hundredths, and 5 thousandths.
When dividing what number goes first?
dividend
The number to be divided is the dividend. The number by which we divide is the divisor. If 8 ÷ 2 = 4. Here dividend is 8, divisor 2, quotient 4 and remainder 0.
What are 3 ways to interpret the remainder?
Learn how to interpret the remainder in 3 different ways (ignore it, round it, or report it as a fraction or decimal).
Which is quotient and remainder?
3.1 Quotients and Remainders The number of times we have subtracted is called the quotient (of the division of by ) The number that is leftover from after subtracting as often as possible is called the remainder (of the division of by ).
How do you round up to half round down?
Half Round Up (the common method of rounding) The common method of rounding is to make 0.5 go up, so 7.5 rounds up to 8 (see Rounding Numbers). But this is not a law or anything, it is just what people normally agree to do, and we get this: Half Round Down. But 5 can go down if we want.
What is the rule for rounding up numbers?
If the digit is 0, 1, 2, 3, or 4, do not change the rounding digit. All digits that are on the righthand side of the requested rounding digit become 0. If the digit is 5, 6, 7, 8, or 9, the rounding digit rounds up by one number. All digits that are on the righthand side of the requested rounding digit will become 0.
How can we stop the rounding being all one direction?
If there are a lot of 0.5s they all get rounded up and your answer will have a bias. The calculation was a lot easier, but the answer drifted up a lot! How can we stop the rounding being all one direction? We can decide to round towards even (or odd) numbers, or we can just choose randomly. We round 0.5 to the nearest even digit
How do you increment the result of a division?
Another alternative is to use the mod() function (or ‘%’). If there is a non-zero remainder then increment the integer result of the division. Share Follow answered Aug 20 ’08 at 13:30
