What is the decimal of 13 /20

Answers

If you would like to know what is the decimal of 13/20, you can calculate this using the following steps:

13/20 ... multiply both numbers by 5
13/20 = 65/100 = 0.65

The correct result would be 0.65.

Answer: 0.65

Step-by-step explanation: In order to write 13/20 as a decimal, we need to find a fraction equivalent to 13/20 with a 100 in the denominator. Notice that if we multiply both the numerator and denominator of 13/20 by 5, we get the equivalent fraction 65/100 which we can now write as a decimal. The hundredths place is two places to the right of the decimal point so we can write 65/100 as 0.65

Therefore, 13/20 is equivalent to 0.65.

Ashton is saving money to buy a new bike. he needs $120 but has only saved 60% so far. How much more money does ashton need to but a bike?

Answers

The best thing to find out how much he has already saved.
As you're looking for 60%, the best thing to do is to find 10% and then multiply accordingly.
To find ten percent, divide 120 by 10.
therefore, 10% is $12.
As you're looking for 60%, you need to multiply this by 6.
12*6= 72.
So far, Ashton has saved $72, and you're looking for what is left, so you need to subtract this from 120.
120-72= 48
therefore, Ashton needs to save $48 more to buy the bike.

the area of a rectangular patio is 5 5/8 square yards, and its length is 1 1/2 yards. what is the patio's width, in yards

Answers

area = length x width
if the area is 5 5/8, and the length is 1 1/2, all you have to do to find the width is divide the area by the length.
5 5/8 / 1 1/2 = 3 3/4 yards

hope this helped!!
well the area of a rectangle is width times length, so you can flip the equation to say that width = area divided by length, or length = area divided by width :)

How do you know the correct order in which to evaluate algebraic expressions?

Answers

In solving algebraic expressions, there is an order in which to solve it.

1) perform the operation inside the parenthesis first  
2) then perform the operation with the exponents
3) apply multiplication and division from left to right of the equation.
4) apply addition and subtraction from left to right of the equation.

Remember this: PEMDAS for easier recall. (parenthesis, exponents, multiplication, division, addition, subtraction)
To evaluate algebraic expressions there is no order. You just need to follow something called pemdas. The way to remember this is
 
p = please
e = excuse
m = my
d = dear
a= aunt
s = sally
 
So just remember Please excuse my dear aunt sally or pemdas.
   
P = parentheses (Apply from left tor right)
E = exponent (Apply from left tor right)
M = multiplication (Apply from left tor right)
D = division (Apply from left tor right)
A = addition (Apply from left tor right)
S = subtraction (Apply from left tor right)
 
Then solve!
 
Hope this helps!! xD
