1. 7 2/3 + 2 7/12

Mathematics

It's just not realistic to present a list of 12 math questions and ask for the answers to all of them at once.  Please post only one question at a time and please share your thoughts about how to solve that question.

I'll focus on one problem:    <span>7 2/3 + 2 7/12

Here the LCD (lowest common denominator) is 12.  7 2/3 becomes 7 8/12.

Add 7 8/12 and 2 7/12:


 7 8/12
+2 7/12
-----------
9 15/12                15/12 is not a proper fraction.  Write it as 1 3/12, or 1 1/4.

Then your 9 15/12 becomes (9+1)  1/4, or 10 1/4.</span>

4 3/4 X 4 1/7 what is it please help
Y_Kistochka [10]

first you turn the fractions into inproper fractions by multiplying the whole number by the denomonator and adding the numerator

4×4=16

16+3=19

19/4

4×7=28

28+1=29

29/7

keep the denomonators the same. now that you've converted them into inproper fractions you can multiply them

19/4 × 29/7=551/28

there is no way to simplify this answer so this is the final answer

What happens when the line and the slope increase and decrease
Ilya [14]
When you use this formula slope = rise/run like rise over run than you find the slope. rise me y and run means x. So when the line slopes downwards to the right it became negative slope as x increases and when line sloped upward to the right the slope become positive as y decreases. 

formula to find slope: slope = rise/run or y/x
