Answer: .25 and 25% favored math as fav subject

Fraction

A fraction is a way to describe a part of a whole.

Mixed Fraction

A mixed fraction is a fraction that contains a whole number and a fraction whose denominator is greater than the numerator.

Percentage

A percentage is also a way to describe a part of a whole. such as the fraction $\bold{(1)/(4)}$ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given to us,

$\bold{1(2)/(5)}$

Converting the fraction to decimal form,

$\bold{1(2)/(5)=((5* 1)+2)/(5)=(7)/(5)=1.4}$

Converting the decimal to percentage form,

$\bold{1.4* 100 = 140\%}$

Hence, the fraction $\bold{1(2)/(5)}$ can be expressed as 140%.

To solve the problem, you need to convert the fraction into a decimal then into a percent.

1 in fraction form is 1/1 which is 1.0 in decimal form and 100% in percent form.

1/2 is 0.5 (because we are halfing, or dividing 1 from 2) in decimal form. 0.5 is 50% in percent form.

Add the percentages up and you will have the sum of 150%.

Find the point where two lines intersct

Answers

y=2x+3
y=-x
the interssection is the set of points that make both systems true

set them eual to each other since they both equal y
2x+3=y=-x
2x+3=-x
add x to both sides
3x+3=0
subtract 3
3x=-3
divid 3
x=-1

subsitue
y=-x
y=-(-1)
y=1

(x,y)
the intersection is (-1,1)

y=2x+3
y=-x
To find the point, first set them equal to each other:
2x+3=-x
Then, solve for x:
3x=-3
x = -1
y = -x --> y = -(-1) = 1
So the point is (-1,1)

How long will it take a seal swimming at a speed of 8 miles per hour to travel 52 miles❔

Answers

6.5 hours. The reason being is that i did 8x6, and got 48, then realized that another .5 would get me 48+4=52, which would fufill the equation

6.5 hour since 52/8=6.5 you would divide 8 by 52

Write 7/10 as a sum of fractions two different ways.

Answers

$(1)/(10) + (6)/(10) = (7)/(10) \n \n (2)/(10) + (5)/(10) = (7)/(10) \n \n (3)/(10) + (4)/(10) = (7)/(10)$

some fun

$(7)/(10) = (14)/(20) \n \n (9)/(20) + (5)/(20)$ $(14)/(20) = (7)/(10)$

$(7)/(10) = (21)/(30) \n \n (8)/(30) + (13)/(30) = (21)/(30) = (7)/(30)$

7/10 is equal to 3/10 plus 4/10

And

7/10 is equal to 5/10 plus 2/10,
