Andy is one-forth as old as his grandfather, who is 76 years old. write an equation to determine whether andy is 19 or 22 years old.

76÷4=19

Step-by-step explanation:

Timesing by quarter (or one-forth) is what you need to do to 76 to work out Andy’s age. That is exactly the same dividing by 4. So if you do 76÷4 you get 19

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
