25 = 5^2
90 = 2 . 3 . 3 . 5
GCF is not as greedy as LCM.
GCF is just on a diet, so it takes the same number and the smallest amount.
25 and 90 both have 5.
5^2 or 5 ?
Take the smaller one.
GCF = 5
Answer:
159.4
Step-by-step explanation:
I'm assuming that it's supposed to be 15x^3-12x^2 because when you copy and paste the "^" gets cut out
15*2.5^3 - 12*2.5^2 = 234.375 - 75 = 159.375
rounded is 159.4
You need to multiply 15/1 X 3X5.
<span>Multiply the numerators (15 and 3) to get 45. </span>
<span>Multiply the denominators (1 and 5) to get 5. </span>
<span>So now you have reduced the fraction to 45/5 </span>
<span>Simplify it. 5 goes into 45 9 times. </span>
<span>9 is your answer.</span>
