There are a few ways to write 7/10 as a decimal. You can divide 7 by 10 and get the answer as .7, or you can multiply 10 by .7 and get the answer as 7. Alternatively, you could use a calculator to get the answer as .7.
1. The Basics
A decimal is a number that is represented by a fractional part of a whole number. A decimal can be written as either a fraction or as a decimal point followed by a series of numbers. For example, the decimal 0.5 can be written as the fraction 1/2 or as .5.
To write 7/10 as a decimal, divide 7 by 10 and round the answer to the nearest tenth. The answer is 0.7.
2. Rounding
When you are rounding decimals, you are rounding to the nearest tenths place. This means that you are rounding to the nearest number that is divisible by 10. For example, the number 7.48 would be rounded to 7.5, because the number 8 is divisible by 10. The number 7.49 would be rounded to 7.4, because the number 9 is not divisible by 10.
3. The 7 Rule
The 7 Rule states that when you are rounding a number to the nearest tenths place, you can always round up if the number is 5 or more and round down if the number is 4 or less. For example, the number 7.48 would be rounded up to 7.5, and the number 7.47 would be rounded down to 7.4.
4. The 10 Rule
The 10 Rule states that when you are rounding a number to the nearest tenths place, you can always round up if the number is 9 or more and round down if the number is 8 or less. For example, the number 9.48 would be rounded up to 9.5, and the number 9.47 would be rounded down to 9.4.
5. Mixed Numbers
When you are working with mixed numbers, you always want to convert them to fractions first. To convert a mixed number to a fraction, divide the whole number by the denominator (the bottom number of the fraction). Then multiply the result by the numerator (the top number of the fraction). For example, the mixed number 3 1/2 would be converted to the fraction 3/10 by dividing 3 by 10 and multiplying by 2 (since 1/2 is the same as 2/10).
6. Adding and Subtracting Decimals
When you are adding or subtracting decimals, you always want to line them up so that the decimal points are directly across from each other. Then add or subtract the numbers in the same way that you would add or subtract whole numbers. For example, the decimals 5.43 and 2.37 would be added together like this: 5.43 + 2.37 = 7.80.
7. Converting Decimals to Fractions
To convert a decimal to a fraction, divide the decimal by the largest power of 10 that is less than or equal to the number in the decimal place farthest to the right. For example, to convert 0.8 to a fraction, divide 8 by 10 because 10 is the largest power of 10 that is less than or equal to 8. The answer is 8/10 or 0.8
