Explanation:

1.Ratios are used to compare quantities. Ratios help us to compare quantities and determine the relation between them. A ratio is a comparison of two similar quantities obtained by dividing one quantity by the other. ... Hence to compare two quantities, the units must be the same.

3.A point (small dot) used to separate the whole number part from the fractional part of a number. Example: in the number 36.9 the point separates the 36 (the whole number part) from the 9 (the fractional part, which really means 9 tenths).

5.I am thinking its A 11:19 coz,its just asking to how many boys and its ratio to the number of girls,and as you can see,30 minus 11 is 19,means 19 is the number of pupils as boys,i hope it helps
