I think I may be missing something ... I don't completely understand your question.
All you need to make a fraction is two numbers and a bar. The bar can be either
horizontal or slanty. Then you write one number on top and the other number on
the bottom, and bada-bing, you have a fraction.
You can make fractions like
2700 / 600
27 / 6
9 / 2 (all 3 of these have the same value)
600 / 2700
6 / 27
2 / 9 (all 3 of these have the same value)
Answer:
Boys : 210
girls: 240
Step-by-step explanation:
7+8=15
450/15=30
boys: 30*7= 210
girls: 240
to make sure......
210+240=450
The answer is 4.5, since 1 & 8 are in the middle you add those two numbers and divide by two so 1+8=9 and 9/2=4.5
