anyways answer is 268 coins'

Just blurting out the answer serves absolutely no purpose, it merely

allows the student to cheat by entering the answer online without even understanding the solution.
If you want to help, explain what is happening, such as:

dimes : pennies = 5 : 4 = 55:44 = 55x : 44x
quarters : dimes = 7 : 11 = 35:55 = 35x : 55x
( I made the ratio part for dimes to be the same)
quarters : dimes : pennies = 35x : 55x : 44x
for a total of 134x coins

we know 44x = 88
x = 2
so we have 70 quarters, 110 dimes and 88 pennies for a total of 268 coins
