Answer:
38 1/4
Step-by-step explanation:
First I convereted 8 1/2 and 4 1/2 to fractions, because it is easier for me, which gives you
8.5*4.5
Multiplying this out you get 38.25, which is equal to 38 1/4.
If you do it by fractions you convert them to inproper fractions.
8 1/2= 17/2
4 1/2= 9/2
You then multiply and get 153/4
When you divide 153 by 4 you get 38 1/4

Mrs. Wang is 38 years old and her daughter is 15 years old.
Step-by-step explanation:
Explanation:
Let
x
=
the daughter's age
Mrs. Wang is
23
years older, so her age is
x
+
23
In five years, the daughter will be
x
+
5
years old
In five years, Mrs. Wang will be
x
+
23

5
=
x
+
28
years old
And, in five years the sum of their ages will be 63, so...
x
+
5

x
+
28
=
63
Combine like terms

Answer:
20/10 goes to neither since it equals 2
0.02 goes to 2/100 since it is the same as 0.02
200 goes to neither because it is over 2/10 and 2/100
0.20 goes to 2/10 since 2/10 is equal to 0.20
2.0 goes to neither because it equals 2
Hope this helped
