Question: Hi, here is the Math problem that my daughter needs help with: Last summer, at Camp Okey-Fun-Okey, the ratio of the number of boy campers to the number of girl campers was 8:7. If there were a total of 195 campers, how many boy campers were there? How many girl campers? I know the answer is 104 boy campers and 91 girl campers but my daughter and I are not coming up with this answer. Can someone please help? Thank you.

8 boys to 7 girls. You can also say 8 boys out of 15 campers. 8:15::x:195 8*195 = 15x 1560 = 15x 104 = x

You set 16/4 equal to a/1. Then cross multiply 4 and a likewise, cross multiply 16 and 1. Then the equation simplifies to 4a = 16. Isolate/Solve for a. 16 divided by 4 is 4. thus a = 4

This is simple algebra: 16/4 = a/1 Solve for a. The 1 can simply be dropped from the a/1 term and 16/4 = 4. This leaves us with 4 = a. Cross multiplication also works for this problem. So the answer is a = 4. However, I don't think sixth graders are expected to know algebra now that I think about it. The best way to present this to them would most likely be: (1) Divide the side that we have both numbers for: For this example 16/4 = 4. (2) Figure out what ratio on the remaining side will equal 4: In this case what value must 'a' be for a/1 = 4? Obviously 'a' must equal 4 in this case.

8 out of 15 students are boys. 8:15 = x:195 Cross multiply 15x=1560 x=104 104 boys, 195-104 = how many girls.

Let A=Apples. O=Oranges. M=Mangoes. A/O=6/5, O/M=7/2. So 5A=6O and 2A=7M. Thus 5A=6O and O=7/2M Plug in this O into 5A=6O. So we get 5A=21M. Thus (21/5)M=A. Divide by M. So we get 21/5=A/M This is the ratio of apples to mangoes. E

First you will possibly convert the two ratio into fractions that's 2/3 and four/3 then you definately might circulate multiply 3*4 divide it by 3*2 which equivalent 12/6=2 then you definately multiply 2 and 32 which supplies sixty 4 sunflowers. wish this helps you =D
