Answer:
Eleana is 20 years old.
Her grandfather is 80 years old.
Step-by-step explanation:
Suppose Eleana's age is "x". That means her grandfathers age is 4x.
x+4x= 100
5x=100 Divide both sides by 5
x=20 That means Eleana is 20 years old.
Her grandfather would be 4 times her age so his age would be 40 years old.
Answer:
(x/12)
Step-by-step explanation:
if 12 pieces combine to make x, [we know they are identical], each piece must be 1/12 of x [1/12·x = x/12]
(think of it like this: "x" length must be divided amongst 12 pieces, so, we divide x/ 12)
