equivalent fractions are fractions which have the same value.
equivalent fractions all have the same simplified form
we can write equivalent fractions by multiplying both numerator and denominator by the same number. We can also write equivalent fractions by dividing both numerator and denominator by the same number
so 5/10
we can get the equivalent fractions by multiplying by a common number
when we multiply by 2
when we multiply by 3
when we multiply by 4
the three equivalent fractions are
10/20 , 15/30, 20/40
Answer:
A. 2006
Step-by-step explanation:
Given:
Number of male drivers model by equation 
Number of female drivers model by equation 
Where 
⇒ the number of years since 1980
We need to find when will the number of licensed male drivers in the U.S. equal the number of licensed female drivers in the U.S.
Solution:
Now we can say that;
to find number of years when the number of licensed male drivers in the U.S. equal the number of licensed female drivers in the U.S we need to make both the equation equal we get;
Now Combining the like terms we get;
Now By using Division property dividing both side by 334.89 we get;
Now x is number of years after 1980.
So we can say that;
26 years after 1980 is 2006.
Hence Approximately in the year 2006 the number of licensed male drivers in the U.S. equal the number of licensed female drivers in the U.S.
Answer:
1 and 3/4 days are equal to 42 hours
Step-by-step explanation:
42 hours = (42 hours) (1 day / 24 hours)
42 hours = 42/24 days
Simplyfing the fraction: Dividing the numerator and denominator by 6:
42 hours = (42/6) / (24/6) days
42 hours = 7/4 days
42 hours = (4+3)/4 days
42 hours = (4/4+3/4) days
42 hours = 1 3/4 days
Answer:
See explanations below
Step-by-step explanation:
Let the amount of nickel be x
Let the amount of pennies be y
Let the amount of quarters be z
If the the total value of the coins is 3.88, then;
x+y+z = 3.88 .... 1
If Anita has 4 more nickels than pennies, then;
x = y + 4 ... 2
If she has 2 more than 4 times the number of quarters than pennies, then;
y = 2 + 4z
4z = y-2
z = (y-2)/4 ...3
Substitute 2 and 3 into 1
y+4+y+(y-2)/4 = 3.88
4y+16+4y + y-2 = 15.52
9y + 14 = 15.52
9y = 15.52 - 14
9y = 1.52
y = 1.52/9
y = 0.17
Since x = y + 4
x = 0.17+4
x = 4.17
z = y-2/4
z = 0.17-2/4
z = -1.83/4
z = - 0.46
