35/56 and 36/56
first find writ out all of the multiples of each
8: 8,16,24,32,40,48,56,64,72,80...
14: 14, 28, 42, 56, 70, 84,98, 112...

next find the number that each of them have in common
8: 8,16,24,32,40,48,56,64,72,80...
14: 14, 28, 42, 56, 70, 84,98, 112...

then set up a proportion to look like this
8: 5/8=x/56 (cross multiply) x=35
14:  9/14=x/56 (cross multiply) x=36

lastly make 56 your denominators and the x's your numerator...your end result should be:
35/56 and 36/56

The denominator is the bottom portion of the fraction. Example 4/6, the 6 is the denominator. The easiest way to start out in finding the common denominator is to see what number, 8 and 14, go into equally. Example: 1/4 and 1/3, 3 and 4 both go into 12. If you multiply 4 by 3 as well as 3 by 4 you get 12 both times. Now try it with 8 and 14.

What number can 8 and 14 go into equally? (56)

8x7=56...14x4=56

On a drive from one city to​ another, Victor averaged 5151 mph. If he had been able to average 7575 ​mph, he would have reached
Vitek1552 [10]

Answer:

d=1.416.525 mile

Step-by-step explanation:

V1=5151m/h, t1=t, V2=7575m/h, t2=t-88h

d1=d2 Because it is same distance; V1=d1/t and V2=d2/(t-88) but d1=d2

d=V1t=V2(t-88) → 5151t=7575(t-88) → 5151t=7575t-666.600 → 7575t-5151t=666.600 → 2424t=666.600 → t=666.600/2424 → t=275h so

d=5151\frac{mile}{h}.275h =  1.416.525mile

Hello, I need this to be answered asap, it's attached and I also have more questions too.
Angelina_Jolie [31]

Answer:

2.33 x 3.26 = 6

32.13 x 2.26=64

523.1 x 9.71=5,230

2561/20.36=128.5

7.6 x 3.89=32

38.89 x 52.25=2028

1826/19.51=91.3

201.21 x 65.63=13,266

Step-by-step explanation: Again, going by what you said, 2.33 would round to 2. So, on the paper attached, I rounded all the numbers to the nearest whole number and then I multipled them. To clarify, if the answers need to be rounded to the nearest whole number as well, then 91.3 would be 91 instead and 128.5 would be 129 instead
