Answer:
number is 6
Step-by-step explanation:
let the number be x , then double the number is 2x and
2x - x = 10 ( multiply through by 3 to clear the fraction )
6x - x = 30
5x = 30 ( divide both sides by 5 )
x = 6
That is the number is 6
To make it easier, I’m going to make the fractions so that they both have the same denominator. To do this i have to multiply both the top and the bottom of one fraction by the other fractions denominator for both fractions.
When i do that, I get:
swimming: 8/40
tennis: 15/40
If you add those fractions together, you will get 23/40.
40-23=17 So, 17/40 of students chose cricket.
