Answer:
11/19
Step-by-step explanation:
Firstly, we need to know the total number of instructors. This is equal to 7+5+4+3 = 19 instructors.
The probability of selecting a science instructor is 4/19
The probability of selecting a math instructor is 7/19
The probability of selecting either a science or a maths instructor is 4/19 + 7/19 = 11/19
Answer:
1/5(14+×)
Step-by-step explanation:
The sum of 14 and x has to be (14+x)
23/5, 5/2, 31/9, and 19/7
All you have to do is multiply the whole number by the denominator and add the numerator. For example:
5 3/6 5*6 is 30 +6 is 36
therefore the improper fraction is 36/6
