Answer:

1/2 <3/4

Step-by-step explanation:

1/2   vs 3/4

We need a common denominator of 4

1/2*2/2   vs   3/4

2/4  vs 3/4

Since the denominators are the same, we compare the numerators

2 <3  so

2/4 < 3/4

1/2 <3/4

Jack is 4 times as old as Lacy. 4 years ago the sum of their ages was 52. How old are they now
Papessa [141]

Answer:

Jack = 48 years old ,  Lac = 12 years old

Step-by-step explanation:

Jack = 4Lacy

(Jack - 4) + (Lacy - 4) = 52

Now, substitute.

4Lacy - 4 + Lacy - 4 = 52

5Lacy = 60

Lacy = 60/5 = 12

Jack =4Lacy

       =4(12)

        =48

I do not remember how to do this please help!
Temka [501]
I think it is self explanatory. Good luck! And remember you can always use long division if you don’t prefer synthetic division. Just rewrite the coefficients in the proper equation. :)
