So we need to solve:
First is important to note that both terms on the left side of the equation have a common factor because they are both divided by y. Then:
Then:
So the solution is y=6. Then option A is correct and you need to write the 6 between the symbols { }.
Ratio of two numbers = 2:3
The larger number = 6
Let the smaller number be x.
Which means :
▪︎<u>Therefore, the smaller number = 4</u>
<h2>○=> <u>Solution (7)</u> :</h2>36 compared to 6 =
Let the number be x.
Which means :
▪︎Therefore, the fractional number is equal to
.
Number of Rose's for 24 red Rose's = 6
This can be written in a ratio as 24:6
Number of roses = 8
Let the number of red roses for these roses be x.
Which means :
▪︎Therefore, 32 red roses are there if there are 8 roses.
<h2>○=> <u>Solution (9)</u> :</h2>Number of children for 2 adults = 7
This can be written in a ratio as 7:2
Number of children in the plaza = 21
Let the number of adults be x.
Which means :
▪︎Therefore, 6 adults were there in the plaza.
<h2>○=> <u>Solution (10)</u> :</h2>Cost of 12 pencils = P60
Cost of 1 pencil :
Thus, the cost of one pencil = P5
Cost of 25 pencils :
= Cost of one pencil × 25
▪︎Therefore, the cost of 25 pencils = P125
The unit rate is 0.25 kilograms per year.
Step-by-step explanation:
Lets define unit rate first
Unit rate is the change in quantity per unit time.
Given
Weight = w = 5 kg
Time = t = 20 years
So,
Hence,
The unit rate is 0.25 kilograms per year.
