(a) The number of females to the number of males.

(b) The number of males to the number of females.

Answer 1

STEP 1 : Given
Total number of persons working in the office = $45$
Number of females working in the office = $25$
Number of males working in the office $=45-25=20$

STEP 2 : Finding the ratio of the number of females to the number of males

(a) Ratio of number of females to the number of males $=\frac{25}{20}=\frac{25÷5}{20÷5}=\frac{5}{4}=5:4$

Hence, Ratio of number of females to the number of males is 5 : 4.

STEP 3 : Finding the ratio of the number of males to the number of females

(b) Ratio of number of males to the number of females $=\frac{20}{25}=\frac{20÷5}{25÷5}=\frac{4}{5}=4:5$

Hence, the Ratio of the number of males to the number of females is 4 : 5.
