Don't look at those size numbers find the ISO (on the sidewall of the original tires) fractional tire sizes can be deceiving -you might end up with English 3 speed tires for your mountain bike as an example, ask me how I know Great article by Sheldon the Brown here - scroll down for table

No it won't fit, not anywhere close in size. Sheldon Brown site explains it.

As a general rule, decimal tire sizes are never the same as fraction tire sizes expressing the same width. In other words, x 1.5 will never be the same as x 1 1/2.

And by the way, 1 3/8 is nowhere near the same as 1.75.
