Let t represent Todd's age now.
.. 4(t -3) -(t -3) = 81 . . . . . . 3 years ago, their differnce in ages was 81.
.. 3t -9 = 81
.. t = (81 +9)/3 = 30
Todd is 30 now.

You can also work this by considering "ratio units." 3 years ago, the ratio of their ages was 4:1, a difference of 3. That difference corresponds to 81 years, so each "ratio unit" represents 81/3 = 27 years. Todd's age then was 1 ratio unit, 27 years. Now, Todd's age is 30.
Answer:
n + n+1 + n+2 + n+3 = 230
4n = 224
n = 56 and largest number = 59

Answer:
7 9/10
Step-by-step explanation:
First, we need to add 4 2/3 and 5 2/5.
We should begin with converting the fractions into improper fractions.
4 2/3 + 5 2/5= 14/3 + 27/5
Now, we find the common denominator
= 70/15 + 71/15
We can add:
= 141/15
And simplify.
= 9 2/5
Finally, we subtract 1 1/2 from 9 2/5
Your answer is 7 9/10. Hope this helps!
