What is 9/10 divided by 3.8 ? By quotient

Given:

divided by 3.8.

To find:

The quotient.

Solution:

We have,

divided by 3.8.

Mathematically it can be written as

Convert the decimal into fraction by multiplying and dividing by 10.

      [Reciprocal rule of division]

                    (Cancel out the common factors)

Therefore, the quotient is , which is approximately 0.237.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
