    What is the effect of decreasing the widths of slits in double slit experiment?

    You get more diffraction so the energy spreads more on the screen instead of being concentrated near the center.

    Will the number of fringes decrease or increase?

    The number or placement of the fringes doesn't change. Their relative brightness changes. Diffraction is required for light to reach the off center fringes.
