To find one tenth of a number, multiply the number by 0.1. For example, one tenth of 23 is equal to 23 x 0.1 = 2.3

Multiply it by 0.01

Multiply it by 0.01

To find one tenth of a number, multiply the number by 0.1, or divide the number by 10.

.1 + .01 = .11 = 11/100

It would be 0.8. The tenth place is one place behind the decimal, so if the hundredth place is 5 or higher the tenth place is rounded up.

either divide by 5 or multiply by 0.2 or find a tenth then double it.

To find one-tenth of a number move the decimal over to the left one place. Also, you can multiply by 1/10 or .1 2.00 * .1=0.2

To find one tenth of 90 you multiply it by the decimal form of one tenth (.1). 90 X .1=9 And you can check the answer by solving 9/90 which equals .1 So the answer is 9.

first simplify the fraction then multiply the denominators times the numerators and see if they are equal

For circumference, multiply the diameter by pi and round the product to the second decimal place. For area, multiply the square of the radius by pi and round the product to the second decimal place.

Either multiply the number by 1/10 or divide the number by 10 or move the decimal point one position to the left

That is necessary if trying to find an equivalent ratio: not otherwise.

multiply the length by the width so a 10 x 10 space will equal 100

To find other fractions that 4/5 is equal to, multiply the numerator and denominator by the same number. For example: Multiply both by 2: 8/10 Multiply both by 9: 36/45 Multiply both by 100: 400/500

That depends what mass a million of these parts hold - then you can multiply it by 0.000166 to find 166 parts per million of this substance.

If the radius is 6 units, the diameter is 12. To find the circumference, you multiply the diameter by pi to get 12pi or 37.699, which rounds up to 37.70.

LM = 4 in LN = ? Find LN. Round the answer to the nearest tenth.

If you want to find one tenth of a number, divide it by 10. For example, one tenth of 50 is 5. I teach my students about fraction this way. When you consider one tenth of something, 1/10, think of the denominator of the fraction as the number of equal groups you have to divide a particular number into. Then think of the numerator of the fraction as the number of those equal groups you are counting up. Another example: to find 3/10 of 50, divide 50 into ten equal groups of 5 each. Then count three of them: 5 + 5 + 5 = 15. 3/10 of 50 is 15.
