What is the answer to 7 plus 24 divided 6x2 equal too?
It depends on how you do it. 1) ((7+24)/6)*2 7+24 = 31 31/6=5.166666667 5.166666667*2=10.333333333 2) 7+((24/6)*2) 24/6=4 4*2=8 8+7=15 3) (7+24) / (6*2) 7+24=31 6*2= 12 31/12= 2.583333333 The normal way would be method (2) which follows the rule of first dividing then multiplying then adding. However when writing out a sum to do it is important to use brackets to make the order in which mathematical operations are to be performed clear because, as you can see, it does affect the result.

What are the values of the fractions when twice a fraction plus thrice another fraction equals 31 showing work?
Let the fractions be x and y:- If: 2x+3y = 31 Then: 2/31x+3/31y = 1 by dividing all terms by 31 So: 2/31*31/4 + 3/31*31/6 = 1 because 1/2+1/2 = 1 Therefore: x = 31/4 and y = 31/6 Check: 2*31/4 + 3*31/6 = 31
