Answer:
3/4 15 3
Step-by-step explanation:
To convert 0.75 to a fraction:
Divide it by 1:
Multiply both the top and bottom by 100: (this is called a decimal fraction)
Simplify the fraction by dividing both the top and bottom by 25:
(this is called a common fraction)
1 cent = 0.01 = 1/100 = 1 hundredth
1 nickel is worth 5 cents = 0.05 = 5/100 = 5 hundredths
1 quarter is worth 25 cents = 0.25 = 25/100 = 25 hundredths
Therefore, to calculate how many nickels represent 0.75 (75 hundredths) divide 75 by 5:
75 ÷ 5 = 15
To calculate how many quarters represent 0.75 (75 hundredths) divide 75 by 25:
75 ÷ 25 = 3
