Answer:
1/2 ÷ 4 = 8
Step-by-step explanation:
Dividing fractions is as easy as pie. Flip the second and multiply.
1/2 ÷ 4 = 1/8
A whole number secretly has a 1 underneath, like this: 4/1
Flip the second number over to get 1/4, then multiply straight across.
×
= 
Try to do the same for the other answers and see if they're right (they're not).
1/8 x 1/6 = 1/48
1/3 x 1/4 = 1/12
1/9 x 1/2 = 1/18
77.2%
To find the probably and at least on you must find the probability of none and subtract from one.
The probability of none can be found like so:
(5+6 over 5+6+7)^3 = .228
1 - .228 = .772
Hope this helps!
Answer:
You got about 52 (~51.975) questions right on your chemistry exam
You got a 93.1% on your biology exam
Step-by-step explanation:
55 multiplied by 0.945 gives you about 52
And for the second part just divide 54/58 to get the percentage
