Answer:
90
Step-by-step explanation:
1/2x10x3.6=18
18x5=90
Perimeter is all four sides added together, therefore....
38+38= 76
8dm= 80cm
80cm*2=160 cm
76+160= 236<span />
Subtracting a negative is the same as adding it.
4-(-3)=4+3=7
In order to find a fraction, We know that a percentage is out of a 100. This means we can now place our fraction as:
38/100
In order to find the actual fraction, we will want to simplify. Lets find our least common factor and work down from there. Since we know that 2 can go into both of them, lets reduce by 2.
This means our fraction will now look like:
19/50
Since 19 is a prime number and cannot be divided by anything but 1 and itself, we know that this is our simplified form.
This means:
19/50 is the fraction equivalent to 38%.
