Answer:
75% of 400 is 300. Equation- (75×400) ÷ 100=300 (Im not sure what the model is because it was not included in this question but hopefully this helped solve the first part of your question.)
Explanation:
Multiple 75*400
You would get 30,000, then take that 30,000 and divide it by 100
You get 300, which is the answer for the first part of the question.
