Hello,
Please, see the attached file.
Thanks.
when we divide a fraction, we flip the denomonator and numerator and then multiply by the fraction. So flipped 1/3 become 3.By multiplying 8 by 3 gave the same answer as in the 1st problem.
The answers in both problems are the same because of the rule of the division of the fraction
Brad have 19 quarters and 27 nickels.
Step-by-step explanation:
Given,
Total worth of nickels and quarters = $6.10 = 6.10*100 = 610 cents
One quarter = 25 cents
One nickel = 5 cents
Let,
x represent the number of quarters.
y represent the number of nickels.
According to given statement;
25x+5y=610 Eqn 1
y = x+8 Eqn 2
Putting value of y from Eqn 1 in Eqn 2

Dividing both sides by 30

Putting x=19 in Eqn 2

Brad have 19 quarters and 27 nickels.
