There are 3 times as many males as females on the maths course at university. What fraction of the course are male?
exis [7]

(1)

If there are three times as many males as females, the ratio of males to females would be 3:1.

To make this more clearer. Suppose you have 100 students. for each 4 students, 3 of them are male and 1 is a female.

We can then say there are 75 males and 25 females.

Expressing this as a ratio(fraction) is easy 3 out of 4 are males and 1 out of 4 are females. So the ratio of males would be;

r(m) =  \frac{3}{4}

(2)

Let x be the number of cola bottles

Let y be the number of smarties

Let z be the number of marshmallows

x=3y (since there are 3 times more x than y)

y=2z (since there are 2 times more y than z)

we know that marshmallows are twice as less as smarties. so for 1 marshmallow you'd have 2 smarties. But we also know that cola bottles should be 2×3=6 since we have 3 times more cola bottles than smarties.

Adding up our total sweets we get;

1+2+6=9

But how many of those are cola bottles? 6!

So the ratio of cola bottles can be expressed as,

r(c) =  \frac{6}{9}  =  \frac{2}{3}

You can simplify the numerator and denominator by 3 to get 2 over 3.

Gabrielles age is three times mikhals age. The sum of their ages is 44. What is MIkhails age?
Ymorist [56]
Soln:
Let mikhale's age be X
Gabrielle's age be 3X
Sum of their ages is 44

To find,
their ages.

X+3X=44
4X=44
X=44/4
X=11

mikhale's age= 11

Gabrielle's age = 3x11=33

Sum of their ages 44

Thus we have got their ages.Gabrielle's age is 33 and Mikhale's age is 11.
