3.75 years.

Multiply 1/4 and 63 1/4 x 63= 63/4 Convert 63/4 into decimal 63/4= 15.75 Subtract 15.75 to 12 15.75 - 12= 3.75

The solution is here: Name Present age Future age(x years) Pete 12 12 + x Grandfather 63 63 + x

Equation: 12+x=1/4(63+x) 48+4x=63+xs 4x-x=63-18 3x=15 3 3 x=5 years

Check: 12+x=1/4(63+5) 17=1/4(68) 17=17

X = answer to the question

Based on the problem, Pete's age must be 1/4 of his grandfather's age. Therefore,

4(12+x) = 63 + x 48 + 4x = 63 + x 4x - x = 63 - 48 3x = 15

x = 5

Therefore, the answer to your question is 5 years.

Check: 12 + 5 = 17 63 + 5 = 68

Based on the problem, Pete's age must be 1/4 of his grandfather's age 68 ÷ 4 = 17
