4/5 of the children are boys.
So 1 - 4/5 ie 1/5 of the children are girls.
1/5 = 100 so 1 = 500 ie there are 500 children in all.
4/5 of 500 is 500*4/5 = 400
So there are 400 boys.
To determine the ratio of boys to girls in a family with 4 boys and an unspecified number of girls, we first need the total number of children. If we assume there are ( g ) girls, the total number of children would be ( 4 + g ). The ratio of boys to girls is then ( 4:g ), and the ratio of boys to the total number of children is ( 4:(4 + g) ). Without knowing the number of girls, we cannot provide a specific numerical ratio.

Let the number of girls be ( x ). Since there are three times as many boys as girls, the number of boys is ( 3x ). Together, the total number of children is ( x + 3x = 4x ). Setting this equal to 80 gives us ( 4x = 80 ), so ( x = 20 ). Therefore, there are 20 girls in the group.
A mathematical problem can be given in words, such as: Three boys and two girls walked to school. On the way, they met two boys and four girls also walking to school. How many boys walked to school? How many girls walked to school. NOTE: This website won't show the plus sign so I have to use the word plus. A number sentence would be: 2 boys plus two boys equals 4 boys. 2 girls plus four girls equals 6 girls. NOTE: Your teacher probably will want only the numbers.
There are 6 girls and 24 boys. Algebraic solution: Let G = number of girls, B= number of boys G+B = 30 B = 4G Substitute to form G + 4G = 30 5G = 30 G = 6 B = 4G = 4 x 6 = 24
The girls had to learn in school.
189 boys
I think this is what you are looking for...0.8 = 80%100 = 20%80/20 = 4100 x 4 = 400 boys
Most children attend school, more boys than girls though

The answer depends on whether the children are picked at random. If they were selected from inside a girls' school the probability should be quite close to 0. Likewise, if the children were picked inside a boys' school. If six children are picked at random from a large group of children with an equal number of boys and girls, then the answer is 6C2*(1/2)6 = 15/32 = 0.47, approx.
72 girls and 18 boys for a total of 90.

Yes! And it is the law of most countries. Children have to go to school.
Girls and boys went to school until 12. They where caned. Boys at 12 dig and girls at 12 would get married.
