2 3/4 - 1 1/8=?
Airida [17]
Basically you need to make the denominator (whats on the bottom) the same, lets take the first one for example


2 3/4, lets put this all over 4 for the same denominator.

2=8/4, and then add this to 3/4 to get 11/4.

the second part will work the same way,

start by making 1 into 8/8. add this to 1/8 to get 9/8


now we have to add 11/4 and 9/8. to do this, you have to find the smallest multiple between the two (for example: between 6 and 4 it would be 12, since 4*3= 12, and 2*6=12)

now, the smallest common multiple between 4 and 8 would just be 8


11/4= 22/8, since you multiply the bottom and top by the same amount so it still equals 11/4, but your denominator will now be 8.


now you can subtract. 22/8- 9/8= 13/8


final answer: 13/8


try the rest yourself since this is important for later math, hoped this helped :)

The following data shows the number of music shows 20 students of a class watched in a month:
3241004551 [841]

Answer:

The 2nd one.

Step-by-step explanation:

First, put the numbers in order from least to greatest. This isn't required, but it makes it easier.

3 4 4 4 4 4 4 4 7 7 8 9 10 10 13 13 19 19 19 20

Then, for each range of shows watched (0-5, 6-11, etc.) from the graph, count how many numbers from the list fit into that range.

Use the process of elimination:

In 3 4 4 4 4 4 4 4 7 7 8 9 10 10 13 13 19 19 19 20, numbers from 0-5 show up 8 times, so you can rule out the last 2 graphs. Numbers 12-17 show up 2 times, so the first one is incorrect. That leaves you with the second histogram.
