14 quarter inches is 3 and a half inches
Hope this helped :)
Always use the inverse (opposite) operation. Ex. is 2x+4=10.
First subtract 4, and then divide by 2.
actually reverse of order of operations to solve.
This written out is:
2/5 + 4/3
------------
3/5
Roughly, now first we need to change the denominators to all match up in order to properly solve this problem.
Both 5 and 3 go into 15, 5 goes into 15 3 times and 3 goes into 15 5 times. With that said, multiply the individual numerators by 5 and 3.
2/5 -> 2*3/15 -> 6/15
4/3 -> 4*5/15 -> 20/15
3/5 -> 3*3/15 -> 9/15
With this, we then add the top numerator of the overall problem:
26/15
------- | With this we now cross-multiply.
9/15
26/15 * 15/9 = 390/135 | Now to simplify this.
135 goes into 390 twice, as 270. Subtract 390 by 270, leaving us with 120.
Meaning: 2 120/135 is the answer, but now to simplify. Divide 120 and 135 by 5 to lessen this.
24/27 | Divide this by 3 to get your most simplified answer.
8/9 | Leaving us with the answer of:
2 8/9
I hope this helps, have a great rest of your day! ^ ^

Let x be the number of 52 cent stamps that Sally has and let y be the number of 34 cent stamps that she has.
Then,
52x + 34y = 1150 --- (1)
Also, she has six more 34 cent stamps than 52 cent stamps.
Therefore, y = x + 6
(1) becomes
52x + 34(x + 6) = 1150
52x + 34x + 204 = 1150
86x + 204 = 1150
86x = 1150 - 204
86x = 946
x = 11
and y = 11 + 6 = 17
Hence, Sally has eleven 52 cent stamps and seventeen 34 cent stamps.
