Question

Explain how you decide where to place the decimal in the quotients for a and b.

16.5 divided by 10
16.5 divided by 100

Answer 1

1.65

0.165

For example, .000 is in the hundreds place to the right and .00 is the tens place.

Answer 2

a)
`(16.5)/(10)=1.65`

b)
`(16.5)/(100)=0.165`

Explanation:

Given : a) 16.5 divided by 10

b) 16.5 divided by 100

To find : Explain how you decide where to place the decimal in the quotients for a and b ?

Solution :

Placing the decimal in the quotients,

If the value is multiple of 10 then the decimal is placed to the right according to number of zeros.

For example -
`(3)/(10)=0.3` it place one value to the right.

Now, We solve the expressions

a) 16.5 divided by 10

i.e.
`(16.5)/(10)=(165)/(100)=1.65`

b) 16.5 divided by 100

i.e.
`(16.5)/(100)=(165)/(1000)=0.165`
