The Ratio of the boy's allowance to his sister's is 5 : 4.
The new Ratio is 1 : 10000.
<h3>What is definition of ratio?</h3>
- The quotient of two mathematical expressions, 1a. b: the proportion between two or more items in terms of quantity, amount, or size.
- What does the arithmetic term "ratio" mean?
- An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.
- For instance, if there is 1 boy and 3 girls, you may express the ratio as 1: 3 (there are 3 girls for every boy), meaning that there are 1 in 4 boys and 3 in 4 girls.

Answer:
2:25
Step-by-step explanation:
Time=distance/speed
81/36=2.25
2:25 is the time for how long this will take!
Lets answer this:-
1st lets divide to see how many times 28 goes in 8. And then we will multiply....
28 ÷ 8 = 3.5
Now lets multiply to see how many symphonies are equal to 25 concerts. Lets do it:-
3.5 × 6 = 21
So, 21 symphonies are equal to 28 concerts.
Lets divide to see how many concerts are equal to 42 symphonies and the multiply to get our final answer.
42 ÷ 6 = 7
7 × 8 = 56.
So, 56 concerts are equal to 42 symphonies.
Hope I helped ya!!
8/15 = 56/105
This may be solved using proportion.
a/b = c/d
ad = bc where cross products are equal.
a = 8
b = f
c = 56
d = 105
ad = bc
8*105 = f*56
840 = 56f
840/56 = 56f/56
f = 15
56 ÷ 7 = 8
105 ÷ 7 = 15
