Explain and write ratios. If a computer display mode is 640 pixels (picture elements) by 480 pixels, we can write that as a ratio in simplest terms...

If we have two computers, and Computer A transmits five web pages in two seconds to a server, and Computer B transmits twenty pages in ten seconds to a server, are these two computers transmitting at the same speed? (Are these two rates proportional?)

Please help me with these problems, I don't understand.
