Answer:
The required ratio is 9 : 61
Explanation:
Given,
$72 for 488 photos,
That is, the price of 488 photos = 72 dollars,
So, the ratio of price of photos and number of photos =
![(72)/(488)](https://img.qammunity.org/2020/formulas/mathematics/college/ul0hnt0mtss9vnw2zvi4xqtiaibfwn34n1.png)
∵ HCF(72, 488) = 8,
Thus, the ratio of price of photos and number of photos =
![(72/ 8)/(488/ 8)](https://img.qammunity.org/2020/formulas/mathematics/college/p9dk8qh1tvmmx7a2iqapqxney454efimcs.png)
=
![(9)/(61)](https://img.qammunity.org/2020/formulas/mathematics/college/dh12wn0c7gadqdrqfu4f3wikz0fwsci41k.png)
