The fraction 4/5 is equivalent to 0.8 and to 80%. how do i write 0.8 and 80% as unreduced fractions.

8/10; 80/100

Step-by-step explanation:

0.8 means "8 out of 10". The equivalent unreduced fraction is 8/10.

80 % means "80 out of 100". The equivalent unreduced fraction is 80/100.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
