The <em>correct answer</em> is:
3 1/2.
Explanation:
To find out how many 1/4 tsp doses are in 7/8 tsp of medicine, we divide:
7/8 ÷ 1/4
To divide fractions, flip the second fraction and multiply:
7/8 × 4/1
Multiply straight across:
7/8 × 4/1 = (7×4)/(8×1) = 28/8
To simplify this, we see how many times 8 will divide into 28. It divides evenly 3 times; this is our whole number.
After 8 goes into 28 3 times, there are 4 left over. This is the numerator of our fraction (8 is the denominator):
3 4/8 = 3 1/2

It could be? the 7 could be 7 to literally any number soooo
Answer:
10 classes
Step-by-step explanation:
Ok, so to solve this we have to make two different equations. we can say 60x = y, or $60 per month, and 6a = b, or $6 per walk in. Since we want the options to end up costing the same, we can say that y = b. With substitution, we get that 60x, (60 per month) = 6a (6 per drop in). The question says we have 1 month, so x = 1. This means we have 60 = 6a, and a = 10 (10 classes).
Total numbers = 32
We are to select 7 numbers at a time. Selecting 7 numbers from a group of 32 is a combination problem. It is similar to making combination of 32 objects taken 7 at a time.
So total possible combinations of 7 numbers can be calculated as 32C7.
32C7 = 3365856
Only 1 combination can match the randomly selected combination.
So, the probability that he combination of 7 numbers will match the seven randomly selected balls =
