How many girls are in the marching band? and how can i turn 3/10 into a number

The answer is 40

Step-by-step explanation:

28/x=7/10

firs you need to setup this equation and solve it to get 40

there are 12 girls in the band and 28 boys in the band and I know this because 12+28=40 just like 3/10 + 7/10= 10/10

12 divided by 4 is 3

28 divided by 4 is 7

there is no points to select.

step-by-step explanation:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
