Question

Ilka and grandma are 72 years old together. Grandma is five times as old as Ilka. How old is Ilka? Solve with an equation.​

Answer 1

12

Explanation:

g+I = 72

I * 5 = g

(I*5) + I = 72

6i = 72

I=72/6

I = 12

Answer 2

let ikas age be x

then grandma will be 5x

so equation will be

`5x + x = 72 \\ 6x = 72 \\ x = (72)/(6) \\ \\ x = 12 \\`
