How do you write the rational number 10.5 in the form a/b? can you me.

21/2

Work Shown:

10.5 = 10 + 0.5

10.5 = 10 + (1/2)

10.5 = (20/2) + (1/2)

10.5 = (20+1)/2

10.5 = 21/2

Alternative Route:

10.5 = 10.5/1

10.5 = 105/10 <--- multiply top and bottom by 10

10.5 = (21*5)/(2*5)

10.5 = 21/2 < cancel the common factors

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.
