Answer:
3/8 & 4/8
Step-by-step explanation:
1/2 - 1/8 = 4/8 - 1/8 = 3/8
x - 1/8 = 3/8
x = 4/8
This is how I would solve it, I would act as if there were 36 people in the class.
36÷6=6×5=30
30÷3=10×2=20
20/36=10/18=5/9
You could also try another number such as 24;
24×(5÷6)=20
20×(2/3)=13.3(3 repeating)
13.333/24=5/9
5/9 people have dogs.
Tell me if this helps.
X = -3, y = 2 rise over run
You need to get a common denominator. 3/4= 9/12 because 3x4=12 and 3x3=9. you must do the same thing to both sides. 1/3=4/12 because 3x4=12 and 1x4=4.
2/6=4/12 because 6x2=12 and 2x2=4. 9/12+4/12+4/12=17/12, or 1 5/12. You keep the denominator and add the numerators.
