You need a common denominator to add fractions. 12 is the smallest number divisible by 4 and 6. 3/4 = 9/12 2/6 = 4/12 9/12 + 4/12 = 13/12 = 1 1/12

**Math Stil don't know how to do this problem :(**

You could turn them both into improper fraction. 15 1/6 would now be 91/6. Then 6 5/12 would be 77/12. 6 and 12 common denominator is 12 so 91/6=182/12. 77/12 = 77/12. 182/12- 77/12= 105/12. Then you turn 105/12 into a mixed number which would be 8 9/12= 8 3/4.

area of sides = 2 L *6 + 2 W*6 = 12 L + 12 W area of bottom = L W total area = L W + 12 L + 12 W = 480-4*36 so L W + 12 L + 12 W = 336 but L = W + 4 (W+4)W + 12(W+4) + 12 W - 336 = 0 W^2 + 28 W -288 = 0 (W -16)(W+18) = 0 W = 16 L = 16+4 = 20

First find the common denominator. 12 is the smallest number that 4, 2, and 3 go into. 3/4 = 9/12 1/2 = 6/12 1/4 = 3/12 2/3 = 8/12 Now you can put them into order.

Your first answer is right. But the second problem has a similar flaw to the one we discussed a few minutes ago. The problem ask us to find the number of starbursts Chad had left. 12 - (2 + 3) = 7 pieces left None of your answer choices is correct. 12 - (2/12 + 3/12) = 12 - 5/...

make everything into twelfths, so you have... 9/12k-2/12 =6/12 take out the 2/12 so... 9/12k=8/12 so now you divide 8/12 by 9/12 = 8/12*12/9 = 96/108 and simplify to 8/9 so k = 8/9
