Answer:
88:56 = 11:7
Step-by-step explanation:
Step One
Add the two ratios together 11 + 7 = 18
Now set up a ratio to solve for 11 parts out of 18
11:18 = x:144 Proportion
11 / 18 = x / 144 Equation: Cross mulitiply
11*144 = 18x Combine the left side
1584 = 18x Divide by 18
1584 / 18 = x
88 = x
That is the larger amount (11 is larger than 7)
Find the smaller amount
144 - 88 = 56
The two amounts are in the ratio of 11:7
88:56 = 11:7
I hopes this helps a little bit

Answer:
You have
21
dimes and
7
quarters.
Explanation:
Let
x
be the number of quarters, and
3
x
the number of dimes.
The amount of money you have can be written as
0.25
x
+
0.1
⋅
3
x
=
3.85
.
Now isolate
x
to find the number of quarters:
0.25
x
+
0.1
⋅
3
x
=
3.85
0.25
x
+
0.3
x
=
3.85
0.55
x
=
3.85
x
=
3.85
0.55
=
7
=
the number of quarters.
Then multiply by three to get the number of dimes:
7
⋅
3
=
21
