Question
How many senators are Republicans
Answer:
56
Explanation:
The total ratio is 5+4=9
To find the number of senators who are either Republicans or Democrat, we multiply the total number by proportion of each.
Senators who are Democrats will be 100*4/9=44
The senators who are Republicans will be found by deducting the total number from number of Democrats hence 100-44=56 senators
Alternatively, using proportion, Republican senators are 100*5/9=56
