Question

The ratio of Geoff’s to Ethan’s age is 1:10.If the total of their ages is 88, how old is Ethan

Answer 1

hi there!

The correct answer to this question is: 80 years old

Explanation:

you first need to set up to equations:

in this case: I will use the variable "e" for Ethan and "g" for Geoff

e=10g

g + e = 88

since e = 10g, substitute that into the second equation and you get 10g + g = 88

you add the variables and you get 11g=88 then you divide 11 on both sides and you get 8 so geoff is 8

then you plug 8 back into the second equation and you get ethan's age which is 80

Answer 2

80 years old

Explanation:

the ratio is 1:10 and their total is 88. Just by looking at it you can see that Geoff's age is 8 and Eathan is 80. The total is 88 and the ratio also matches.

1:10 1 times 10 is 10

8:80 8 times 10 is 80
