a piece of paper has a mass of 4.4 grams. a feather has a mass of 8.0x10^-3 gram. the mass of the piece of paper is how many times greater then the mass of the feather

3 answers

To find out how many times greater the mass of the paper is compared to the mass of the feather, we need to divide the mass of the paper by the mass of the feather:

4.4 grams / 8.0x10^-3 gram = 550

Therefore, the mass of the piece of paper is 550 times greater than the mass of the feather.
-11 2/3 x (-4 1/5)
First, we need to convert the mixed numbers to improper fractions:

-11 2/3 = -35/3

-4 1/5 = -21/5

Now, we can multiply the fractions:

-35/3 x -21/5 = (35 x 21)/(3 x 5) = 735/15

We can simplify this fraction by dividing the numerator and denominator by their greatest common factor, which is 15:

735/15 = 49

Therefore, -11 2/3 x -4 1/5 = 49.
