[/fusion_text][fusion_text]When dividing decimal numbers by other decimal numbers, before you just divide, you need to shift the decimal so that it creates a whole number to divide by.[/fusion_text][fullwidth background_color=”” background_image=”” background_parallax=”none” enable_mobile=”no” parallax_speed=”0.3″ background_repeat=”no-repeat” background_position=”left top” video_url=”” video_aspect_ratio=”16:9″ video_webm=”” video_mp4=”” video_ogv=”” video_preview_image=”” overlay_color=”” overlay_opacity=”0.5″ video_mute=”yes” video_loop=”yes” fade=”no” border_size=”0px” border_color=”” border_style=”” padding_top=”20″ padding_bottom=”20″ padding_left=”0″ padding_right=”0″ hundred_percent=”no” equal_height_columns=”no” hide_on_mobile=”no” menu_anchor=”” class=”” id=””][imageframe lightbox=”no” lightbox_image=”” style_type=”none” hover_type=”none” bordercolor=”” bordersize=”0px” borderradius=”0″ stylecolor=”” align=”center” link=”” linktarget=”_self” animation_type=”0″ animation_direction=”down” animation_speed=”0.1″ hide_on_mobile=”no” class=”” id=””] [/imageframe][/fullwidth][fusion_text]In this case before you can divide by 0.08, you have to shift the decimal place 2 spots over, which means you need to shift the decimal 2 spots in the dividend, so that it becomes 722.4 / 8. After you shift the decimal places, then just proceed as normal to divide.[/fusion_text][fusion_text]Remember to always double check for the reasonableness of answers!!![/fusion_text][fusion_text]In the example above, if I rounded 722.4 to 720. I know that 720 / 8 = 90, so my answer should be somewhere around 90.[/fusion_text][fusion_text]
