One minus what number is 0.23

Question

One minus what number equals zero point two three

 

Answer 1

Hi Nikki;

1-0.23=?

1 can also be written as 100/100.

0.23 can also be written as 23/100

(100/100)-(23/100)

The denominators are the same 100.  These will not change.

We will subtract 23 from 100.

(100-23)/100

77/100

0.77
