Answer:
michelle is 56 years old
Step-by-step explanation:
start with madeline you know she's 7, move on to fiona we know she is twice as old as madeline so we mulitply 7 times 2, we get 14. now we know fiona is 14 and in order to find michelles age we multiply times 4 because shes four time fionas age. 14x4=56.
First find fionas age
Fiona is 2x as old as madeline
madeline is 7
mulitply 7*2 which gives you 14
that means fiona is 14
multiply 14 by 4 which gives you 56
michelle is 56
