Answer: the combined time he spent studying is 281/36 hours
Step-by-step explanation:
The first step is to convert all mixed numbers to improper fraction.
On Monday Billy spent 4 1/4 hour study. Converting 4 1/4 hours to improper fraction, it becomes 17/4 hours.
On Tuesday he spent another 3 5/9 hour study. Converting 3 5/9 hours to improper fraction, it becomes 32/9 hours.
The combined time he spent studying answer as a mixed number would be
17/4 + 32/9 = (153 + 128)/36
= 281/36 hours
Answer:
Richard bought 128 total batteries
Step-by-step explanation:
1. Multiply 4 by 4 to find the total batteries in one package
4 * 4 = 16
2. Now we know that there are 16 batteries per package. There are 4 packages in a box. Multiply 16 by 4
16 * 4 = 64
3. 64 represents the total number of batteries in a box. Since Richard bought <u>two</u> boxes, multiply 64 by 2
64 * 2 = 128
Put all the outcomes in number order(small-large) then find the middle number and that is the median.
Eg. 2 2 4 5 10
The median is 4
Eg. 2 3 5 5 6 9
The median is 5
Eg. 1 3 5 7 8 10
The median is 6
AB is 19 because 32 plus 19 equals 51
Ok so, when working to find if a fraction is equal to another you must know what it is cut down by. So 6 / 2 = 3. Now let's break down 7 by 2. It is 3.5 that is not four. So no 6/7 so not equal to 3/4.
