What is 420/15 simplified to

Ghella [55]

So,

In order to simplify a fraction, we have to factor both the numerator and the denominator.
$\frac{420}{15} --\ \textgreater \ \frac{2*2*3*5*7}{3*5}$

Cross out ones.
$\frac{2*2*7}{1}\ or\ 28$

Answer:

Y+5=2(x+1) if (5,10)

10+5=2(5+1)

15=2(6)

15=12

Y+5=2(x+1) if (-1,-5)

-5+5=2(-1+1)

0=2(0)

0=0

Answer: 49/60

Step-by-step explanation:

(1/3+2/5)-1/4-(5/6-7/6)

Primero (5/6-7/6)

5/6-7/6=-2/6

1/3+2/5-1/4-(-2/6)

1/3+2/5-1/4+2/6

2/6=1/3

1/3+2/5-1/4+1/3

2/3+2/5-1/4

2/3=10/15

2/5=6/15

10/15+6/15-1/4

16/15-1/4

16/15=64/60

1/4=15/60

64/60-15/60=49/60
