Kyle read 3 5/6 books and Jan read 2 1/3 books. How many more books did Kyle read than Jan?
Answer:
3 5/6 = 3 10/12
2 1/3= 2 4/12
3-2=1
10/12-4/12= 6/12=1/2
so Kyle read 1 1/2 more books then Jan
Answer:
Kyle read [tex]1 \frac{1}{2}[/tex] books more than Jan
Step-by-step explanation:
Let's put our equation[tex]3 \frac{5}{6}-2\frac{1}{3}[/tex]
They have different denominators so let's look for the [tex]LCM[/tex] to find our common denominator
Find our LCMDefinition of LCM - LCM stands for least common multiple. The least common multiple of two numbers is the smallest number that is a multiple of both of them.
Now let's find our LCM
[tex]6:6,12,18,24,30,36,42\\\\3:3,6,9,12,15,18,21,24,27,30[/tex]
as you can see our [tex]LCM[/tex] is [tex]6[/tex]
Now our fraction is[tex]3\frac{5}{6}-2\frac{2}{6}[/tex]Solve[tex]3\frac{5}{6}-2\frac{2}{6}=1 \frac{3}{6}[/tex] this can be reduced to [tex]1 \frac{1}{2}[/tex]
Kyle read [tex]1 \frac{1}{2}[/tex] books more than Jan

The ratio of students in Class X to Class Y is 2 : 5. There are 24 more students in Class Y than Class X. How many students must transfer from Class Y to Class X so that both classes have equal number of students?
Answer:
The answer will be 12 students. 12 students must transfer from Class Y to Class X so that both classes have equal number of students.
Step-by-step explanation:
Since the ratio is 2 : 5, we would multiply both number to 8 and get 16 : 40.
Now find the average of those two numbers: (16 + 40) / 2 which gets you 28. Now either subtract 16 from 28 or subtract 28 from 40 and you will get 12.
28 - 16 = 12 students
40 - 28 = 12 students.

Peter says if you subtract 16 from my number and multiply the difference by negative 5 the result is negative 50 what is peter's number?
Answer:
Below.
Step-by-step explanation:
If n is the required number:
(n - 16) * -5 = -50
-5n + 80 = -50
-5n = -50 - 80
-5n = -130
n = -130 / -5
n = 26 (answer).
Explain why 4:6 and 8: 10 are not
equivalent ratios.
Answer:
Because when 4:6 is simplified, you get 2:3, but when 8:10 is simplified, you get 4:5
So, they are not equivalent ratios because their simplified ratios are not the same.
Step-by-step explanation:
Hope this is helpful.
Since the value of the given ratios are different they can not be said to be the equivalent ratio.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
It is given that the two ratios are 4:6 and 8: 10.
Ratios with the same value are said to be equivalent. If we multiply both portions of a ratio by the same number, we can create comparable ratios.
The ratio 4/6 is in the lowest term is 2/3 equal to 0.66
The ratio 8/10 is in the lowest term is 4/5 equal to 0.8
The values of both ratios are different.
Thus, the values of the given ratios are different they can not be said to be the equivalent ratio.

Reina's family is taking a road trip. Their car can travel no more than 304 miles without needing to refill the gas tank. They have traveled 221 miles since they last filled the gas tank. Reina knows that the inequality representing this situation is 221 + x < 304. Select from the drop-down menu to correctly interpret the solution of this inequality. Reina's family can drive ______ more miles before they need to refill the gas tank.
Solving the inequality, it is found that the correct interpretation of the solution is:
Reina's family can drive 83 more miles before they need to refill the gas tank.
The amount x of miles they can still travel is modeled by the following inequality:
[tex]221 + x \leq 304[/tex]
To solve it, we treat it similarly to an equality, hence:
[tex]x \leq 304 - 221[/tex]
[tex]x \leq 83[/tex]
Hence:
Reina's family can drive 83 more miles before they need to refill the gas tank.
A similar problem is given at https://brainly.com/question/11713066
The answer prior to this is WRONG. The correct answer is "at most 83" miles.
C=pi/2 what is the area?
Answer:
A=1
Step-by-step explanation:
The formula to find the area of a circle is πr^2, meaning that you divide the diameter in half which is 1. So 1^1 is one. The area would be one.
Hope this helps :)
The area would be one, is, A=1.
What is area of circle?The area of a circle is π multiplied by the square of the radius. The area of a circle, (A) when the radius 'r' is given is πr2. π is approximately 3.142
here, we have,
C=pi/2
The formula to find the area of a circle is πr^2,
meaning that you divide the diameter in half which is 1.
So 1^1 is one.
