To solve this, you need to have a common denominator for both terms. In order to get the equivalent fraction with the common denominator, you multiply each fraction by a version of 1. Here, it seems like our least common denominator (or LCD) is 12. Therefore, you multiply 1/4 by 3/3 and you multipy 2/3 by 4/4 to get 3/12 plus 8/12 = 11/12.
Hope this helps!
If the weight of the bottom box is b then the weight of a stack of four boxes is b + b/2 + b/4 + b/8
= 8b/8 + 4b/8 + 2b/8 + 1b/8
= 15/8 b
A stack must weigh less than 100 pounds
15/8 b < 100
b < 100 x 8/15 = 53 1/3 pounds
If boxes have a minimum weight of 1 pound then
for stacks that contain 4 boxes the range of b is [8, 53 1/3)
and if stacks contain 1 to 4 boxes the range of b is [1, 53 1/3)
If the only restriction is a maximum of 100 then the range of b is [0, 53 1/3)
Hello Syndy393, Which expression is equivalent to 18a+12b+9a+24b,
<span>27a+36b, Because 18a+9a=27a 12b+24b=36b,so the correct answer is 27a+36b.</span>
