6. 24- factors:1&24,2&12,3&8, 4&6. 18 factors: 1&18, 2&9, 3&6. The highest number that can multiply into them is 6 so it is the GCF
The answer should be 4.3 (the line is ontop of the 3)
The line is on the 3
No, it is not 35% off... Let me explain. Let's say the original price is $100 to make the math easy. When you take 25% off then take an additional 10% off, the 10% is off of the discounted price, so
100 x 25% = 100 x .25 = 25 dollar discount
New price = $75
Now 10% off of $75
10% x 75 = .10 x 75 = $7.50 discount
New price = 75 - 7.50 = $67.50
Now, if you just took 35% off of $100
100 x 35% = 100 x .35 = $35 discount
New Price = 100 - 35 = $65
Bottom line... when you take an "extra" percentage off, you are taking a percentage of a smaller number, so the discount is not as big.
