How do you change 4.5 into a fraction?

Answer 1

#4 1/2#
Look at how I did it!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #color(red)("Note: " 0.1 = 1/10 " so " 0.5 " is " 5/10 ;) " " color(green)( 0.01 = 1/100;" "0.001 = 1/1000)#

ด ฟฟ ฟ ฟฟ

#4.5 " is " 4 + 5/10 #

Observe that I am maintaining the same ratio by dividing both the top and bottom by the same number, so this is mathematically possible!

and #(color(red)(5 divide 5))/(color(blue)(10 divide 5)) =(color(red)(1))/(color(blue)(2)#

#4.5 = 4 5/10 = 4 1/2#
