Can someone help me with this there are only blue, red, green and yellow cubes in a bag.
there are 3 times as many blue cubes than yellow cubes and 5 times as many green cubes than blue cubes.
Sarah takes a random cube from the bag.
what is the probability that she chose a yellow cubes give as a fraction in simplest form

Step-by-step explanation:

So say there are x yellow cubes.

Yellow = x

Blue = 3x

Green = 15x

It doesn't say red so I'm going to assume there are none.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
