Solve the following problem first using a tape diagram and then using an equation: In a school choir, 1/2 of the members were girls. At the end of the year, 3 boys left the choir, and the ratio of boys to girls became 3:4. How many boys remained in the choir?

Answers

Answer: 9 boys remained in the choir.

Step-by-step explanation:

Let x be the number of of boys and y be the number of girls.

In a school choir, 1/2(half) of the members were girls.

i.e $x=y$ (1)

At the end of the year, 3 boys left the choir, and the ratio of boys to girls became 3:4.

$(x-3)/(y)=(3)/(4)\n\n\Rightarrow\ 4(x-3)=3(y)\n\n\Rightarrow\ 4x-12=3y$

Put y= x from (1), we get

$4x-12=3x\n\n\Rightarrow\ 4x-3x=12\n\n\Rightarrow\ x=12$

Thus , the number of boys : x= 12

Boys remained in the choir = 12-3=9

Preston, can you please help!!!!! Or anyone else!!!!

Hello!

First you have to find the probability of a pulling a penny

To find this you put the amount of pennies over the amount of coins

There are 12 coins and 5 pennies

This is a 5/12 probability

Next you have to find the probability of then pulling out a quarter

Since you already took out a coin the total amount is now 11

The probability is 4/11

You multiply the two probabilities together to get the probability of them happening one after antoher

5/12 * 4/11 = 5/33

The answer is D)5/33

Hope this helps!
