A group of preschoolers has 30 boys and 13 girls then the ratio of boys to all children would be 30:43.
What is a ratio?
A ratio in mathematics shows how many times one number contains another. For example, if a bowl of fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six. Similarly, the lemon-to-orange ratio is 6:8, and the orange-to-total fruit ratio is 8:14.
A group of preschoolers has 30 boys and 13 girls.
Total children will be = 30 + 13 = 43
Ratio = number of boys/total children
= 30/43.
Hence, if A group of preschoolers has 30 boys and 13 girls then the ratio of boys to all children would be 30:43.

Answer:
x=8
Step-by-step explanation:
Since it is an isosceles trapezium, we know that GF and DE are parallel, and that EF = GD. Since we know that co-interior angles always add up to 180 degrees, we know that:
Angle F (13x+4) + Angle E (9x) = 180
So we can write an equation for x and solve it.
13x+4+9x=180
22x + 4 = 180
22x + 4 - 4 = 180 - 4
22x = 176
22x/22 = 176/22
x = 8
