Pls help i dont care how u do it jast pls help me

1.  35 boys and 28 girls

2.  42 long-sleeved shirts

3.  40 total outfits

Step-by-step explanation:

1.

Ratio of Boys to Girls is 5 is to 4, that means that there are "5" parts boys and "4" parts girls. So that makes:

5 + 4 = 9 parts in total

Total there are 63 kids, so each part would be:

63/9 = 7 kids per part

Now,

5 part are boys so 5 * 7 = 35 boys

and

4 parts are girls so 4 * 7 = 28 girls

2.

Long Sleeved Shirts = 60% of the total

Total is 70

So, we basically need 60% of 70

First, we want to convert 60% to decimal. We divide by 100, that's it! So:

60/100 = 0.6

Now to get the number we simply multiply the decimal of 60% we got, which is 0.6 with the total, which is 70. Thus,

0.6 * 70 = 42

Thus, there are 42 long-sleeved shirts

3.

Lily has 30 dress, WHICH ARE 75% of the total outfits she has.

First of all, what is 75% in decimal?

We divide by 100:

75/100 = 0.75

We can now write:

30 is 0.75 times the total

Right?

Which number's 75% (or 0.75) is 30? This is what we need to figure out!

0.75 * which number would give us 30?

We have to simply divide 30 with 0.75 to get total number of outfits:

30/0.75 = 40 total outfits

7/2

(decimal: 3.5)
