First, we know that when multiplying fractions, we multiply both the numerator and denominator.
so, in 4/9 • 4/5,
4•4 = 16, and
9•5 = 45
so, 4/9 • 4/5 = 16/45.
now, we’ll look for the Least Common Factor
factors are numbers that you can multiply together to = another number.
the LEAST common Factor is the # that is smallest that you can divide both numbers by, in an equation and get a whole number.
for instance, 3•3 and 1•9 are the only ways to get 9, so, the factors are 1, 3, 9
let’s look for the LCF in 16 and 45. -
if we find the ways to get 16, we have:
1•16, 2•8, and 4•4
so, the factors are 1, 2, 4, 8, and 16.
this is called FACTORING :)
the ways to get 45 are...
1•45, 3•15, and 5•9, so the FACTORS are
1, 3, 5, 9, 15, & 45.
- compare the factors of 16 & 45,
none of them are the same besides 1, and we know that dividing these numbers by 1 will not do anything.
because of this, we can not reduce 16/45, so the reduced answer to 4/9 • 4/5 = 16/45
Step-by-step explanation:
The function:
f ( x ) = x * 0.965^t
where x is the initial amount and t is the number of the years
80 = x * 0.965^3
80 = x * 0.89632
x = 80 : 0.89632 ≈ 89
Answer:
The initial amount of animals was 89.

19x+5+16x=180
First, add the x's together:
35x+5=180
Now, subtract 5 from both sides:
35x=180-5
35x=175
Divide both sides by 35 to isolate x:
x=5

Answer:
<u>239 students and 153 non-students attended to the school production of "Our Town"</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Number of tickets of the school production sold = 392
Student ticket cost = US$ 3
Non-students ticket cost = US$ 5
Total collected = US$ 1,482
2. How many students and how many non-students attended?
For answering the question we will use the following equation:
x = Number of students that attended the school production
392 - x = Number of non-students that attended the school production
3x + (392 - x) * 5 = 1,482
3x + 1,960 - 5x = 1,482
-2x = 1.482 - 1,960
-2x = - 478
x = -478/-2
<u>x = 239 ⇒ 392 - 239 = 153</u>
<u>239 students and 153 non-students attended to the school production of "Our Town"</u>
