Answer:

3. $\displaystyle 4,12$

2. $\displaystyle \: \: \: \: \: - \\ 0,46$

1. $\displaystyle 0,875$

Step-by-step explanation:

3. Every 25 is worth 4, and since 3 by 4 is 12, 3⁄25 gets set to ",12", then attach the whole number [4] to it, giving you 4,12.

2. Every 15 is worth 6⅔, and since 7 by 6⅔ is 46⅔, moving the decimal mark twice to the left will give you the above answer, in bar notation, since it is a repeated decimal.

1. Every 8 is worth 12½, and since 7 by 12½ is 87½ [87,5], moving the decimal mark twice to the left will give you 0,875.

I am joyous to assist you anytime.
