Equivalent fractions are those fractions that when simplified, are the same. They reduce to the same fraction in their simplest form.
For example, 12/15 and 24 /30 are equivalent fractions. They both reduce to 3/5 in their simplest form.
Least common denominator: it is the lowest number you can use in the denominator to create a set of equivalent fractions that all have the same denominator.
For example, if you have 3/5 + 1/4 and want to add them, you need to get a common denominator
3/5 = 6/10 = 9/15=12/20
1/4 =2/8=3/12 =4/16=5/20
We can use equivalent fractions to help us find the common denominator of 20
replace 3/5 with 12/20 and 1/4 with 5/20
3/5 + 1/4 = 12/20 + 5/20 = 17/20
Answer:
A. (x + 8, y - 4)
Step-by-step explanation:
When something is translated to the right, x goes up, and when something is translated down, y goes down.
Alternatively, eft means down for x and up means up for y.
3r = 45/x= 45/x= 45
r = 45/3 = 15 mph
The speed of PandD = 15 mph
small frames ($8): s
large frames ($15): L
Cost: 8s + 15L = 239 ⇒ 1(8s + 15L = 239) ⇒ 8s + 15L = 239
Quantity: s + L = 22 ⇒ -8( s + L = 22) ⇒ <u> -8s -8 L = -176 </u>
7L = 63
L = 9
Quantity: s + L = 22 ⇒ s + (9) = 22 ⇒ s = 13
Answer: 13 small frames, 9 Large frames
