The least common denominator is
20 = 2 * 2 * 5
25 = 5 * 5
The least common denominator has two 5s and two 2s.
LCD = 2*2*5*5 = 100
17/20 = 17 * 5/ 20*5 = 85 / 100
21/25 = 21* 4/25*4 = 84 / 100
Talk about close
17/20 > 21/25 <<<< answer
But I hate to have predicted that before hand.
We calculate this by multiplying the number of cookies by the number of boxes:
28*14=(20+8)*14=280+80+32=360+32=392 (that's how I like to count it, there are also other methods)
so she has 392 cookies in common.
Answer:
4x - 3y = 36
Step-by-step explanation:
2/3x - 1/2y = 6
Multiply each side by 6 to get rid of the fractions
6* (2/3x - 1/2y) = 6*6
Distribute the 6
12/3 x - 6/2y = 36
4x -3y = 36
