Out of 50 students in a class, 10 students like Maths but not Science and 15 students like Science but not Maths. If 10 students like neither of both subjects; (i) show the above information in a Venn-diagram
(ii)find the ratio of the students who like Maths to the students who like Science.

ok so if we made a venn diagram it would look like this

math     neither      science

10             |      10    |   15

the ration math to science liking kids is

10:15 or 2:3

Hope This Helps!!!

3 × 5/6 = 15/6 hours (option D)

Complete Question:

Irina is watching a 3 hour movie on TV. The shaded part of the fraction model

below represents the part of each hour that the movie is playing, and the

unshaded part represents the time spent on commercials. Which equation

represents the total number of hours for the movie, not including the time for the commercials?

a) 3+ 5/6 = 8/6 hours

b) 3 x 5/6 = 15/18 hour

c) 3+ 5/6 = 8/8?9 hour

d) 3 x 5/6 = 15/6 hours

The complete information and diagram can be found in:

Step-by-step explanation:

Total time of movie = 3hr

The model shows the amount of time spent on the movie and the amount spent on commercials.

We are required to find the total number of time spend on the movie without including the time spent on the commercials for the 3hours duration of the movie.

From the diagram, the total number of squares in the diagram is seen as a whole = 1

The amount of time the movie is playing per hour = the shaded region = 5/6

The amount of time spent on commercials = 1 - (5/6) = 1/6

After 3 hrs, the amount of time spent in playing the movie = (5/6) × 3hours

= (5/6) × 3

After 3 hrs, the amount of time spent in playing the movie = 15/6

The equation that represents the total number of hours for the movie, not including the time for the commercials: 3 × 5/6 = 15/6 hours
