Write the following as a ratio: 304 calories burned in 56 minutes
IgorC [24]

Answer:

The required ratio is 38 : 7

Step-by-step explanation:

Given,

304 calories burned in 56 minutes,

That is, the number of calories burnt in 56 minutes = 304

So, the ratio of the calories burnt and time in minutes  = \frac{304}{56}

∵ HCF(304, 56) = 8,

Thus, the ratio of price of photos and number of photos = \frac{304\div 8}{56\div 8}

= \frac{38}{7}
