Of the coins in Tricia's bank, 5/7 are quarters. If Tricia has 95 quarters in her bank, how many coins does she have in all.
Is this correct?
5/7*x = 95
(7/5)(5/7)*x = 95
x= 95*7/5 95x7 = 665 665/5=133
x=133
Thanks from a Grandma helping w/4th grade math
Hi Robin
Yep that is correct.
Great thanks Rose.
Yes, your solution is correct! You correctly set up the equation to find the total number of coins.
To solve the equation, you multiplied both sides by the reciprocal of 5/7, which is 7/5. This eliminated the fraction on the left side, leaving you with x = 95 * 7/5.
Next, you simplified the right side by multiplying 95 and 7 to get 665. Then, you divided 665 by 5 to get the final answer, which is 133.
Therefore, Tricia has a total of 133 coins in her bank. Well done!
