8 and 9/10 minus 3 and 1/4 equals
maxonik [38]

Answer:

The correct answer is 17/4, from 8 and 9 from the top PLUS 3 and 1 from the bottom.

Step-by-step explanation:

If we have a mathematical problem, it's important to follow all of the steps. In this instance, we have to reduce our fractions as well as pay attention to how they are grouped together before dividing out what remains. This means that if we break it into three groups - 8 and 9 11/2 groups - 3 and 1 17/4, then divide everything by 4 with a remainder of 2/4....we get a total of 17/4 remaining which is equal to 5 1/8 = 62%.

Find the median<br> 45. 28 37 30 42 44 35 40
jasenka [17]

Answer:

Step-by-step explanation:

The median means the number in the middle, I look at the word median and think mid! So by ordering the numbers from highest to lowest you cross one off from each end back and forth! So you cross off 45, then 28, 44 then 30, 42 then 35 leaving one last number 40!! That is your median :)
