Question

Please help 16 over 20 as decimal and why

Answer 1

Long division is the universal way, but it can also be approached differently.

We know that
`20\cdot5=100`, therefore
`(16)/(20)=(16\cdot5)/(20\cdot5)=(80)/(100)=(8)/(10)=0.8`.

Or simplify
`(16)/(20)` first:
`(16)/(20)=(4)/(5)`. Then using the same logic as above -
`5\cdot2=10`, therefore we
`(4)/(5)=(4\cdot2)/(5\cdot2)=(8)/(10)=0.8`.

Answer 2

Answer: .8

Explanation:

`(16)/(20)` >reduce the fraction first by dividing the top and the bottome by 4

so it is easier to divide

=
`(4)/(5)` >now divide 4 by 5

> 4 cannot go into 5 so you would place a decimal point after the 4 and add a 0

>4.0 divided by 5 is .8

=.8

you get a decimal which is less than 1 because you only have 4/5 which is less than 1 whole so you only get a portion as a decimal.
