<h3>What is ratio and proportion?</h3>
When comparing two quantities of the same kind, ratio is utilized.
For two numbers, a and b, the ratio formula is written as a: b or a/b.
Two or more ratios are said to be in proportion if they are all equal.
Fractions are the foundation of the concepts of ratio and proportion.
Let x is the number of hours the first mechanic worked and y is the number of hours the second mechanic worked.
∵x+y = 20
x = 20 - y
115x+100y = 2225
115(20-y) + 100y = 2225
2300 - 115y +100y = 2225
15y = 75
y = 5 hours
∴ x = 20-5
x = 15 hours

Answer:
3 bags of sour cream and onion crisps
Explanation:
1/4 of 20 is 20 divided by 4 so there are 5 packs of Doritos.
20-5=15 packs still left
1/5 of the remaining bags is 1/5 of 15. 15 divided by 5 is 3.
There are 3 bags of sour cream and onion crisps.
Hope this helped!
