Step-by-step explanation:
If the first number is increased by 30% and the second number by 80%, the sum will be 1.6 times larger than the initial sum. Find the ratio of the first number to the second number.
Answer:
2 : 3
Step-by-step explanation:
Let x represent the first number and let y represent the second number.
Therefore the initial sum of the numbers = x + y
Given that the first number is increased by 30%, it becomes = x + 30% of x = x + 0.3x = 1.3x.
Also, the second number is increased by 80%, it becomes = y + 80% of y = y + 0.8y = 1.8y.
The sum of this increased numbers is 1.6 times larger than the initial sum. That is:
1.3x + 1.8y = 1.6(x + y)
1.3x + 1.8y = 1.6x + 1.6y
1.8y - 1.6y = 1.6x - 1.3x
0.2y = 0.3x
The ratio of the first number to the second number (that is x / y) is:
0.3x = 0.2y
Divide through by 0.3y:
0.3x / 0.3y = 0.2y / 0.3y
x / y = 0.2 / 0.3
x / y = 2 / 3
x : y = 2 : 3

raj has saved $68 for a video game system that cost $200. if he makes $5.50 for each hour he works how many hours will he need to work in order to earn the reminder of the money he needs to buy the gaming system explain the steps you use in order to solve the problem
Answer:
24 hours
Step-by-step explanation:
Divide 200 by 5.50
200÷5.50=36.36 (round to the nearest decimal)
Divide 68 by 5.50
68÷5.50=12.36 (round to the nearest decimal)
So if he worked 12.4 hours to gain $68,
We then can minus 12.4 from 36.4
36.4-12.4=24
He will need to work 24 more hours in order to have enough money

you can work this out by putting the ration in a column eg 2:7
and if you know how many spots are in one column like for the 2 in 2:7 has 114 spots then you need to find oht how many are in that 114! basically just do 114 ÷ 2 =72 then use 72 to multiply the 7 (in 2:7) by 72 which makes 504.

If 480 pupils in a school are boys representing 4/5 of the school enrolment,find the total number of pupils in the school
Answer:
1000
Step-by-step explanation:
Let the total number of children in school be y.
Then according to the question (4/5) of children are boys.
Then as we know that the sum of fractions is 1.
The fraction of girls in school is
1 - (4/5)= (1/5)
So this means (1/5) of the total children in school are girls which means
Y × (1/5) =200 , according to question.
Which gives y =200×5=100
This means that the total number of children in school is 1000.
