Changed the style css in gallery width, but forgot old numbers

Hi, I’m using the free make theme and I changed something (very stupid) in the style.css and I want to change it back, but I forgot the old numbers.

I changed the numbers in this area: @media screen and (min-width: 800px) {
.builder-gallery-columns-1 .builder-gallery-item {
width: 100%;
}

.builder-gallery-columns-2 .builder-gallery-item {
width: 100%;
}

.builder-gallery-columns-2 .builder-gallery-item.last-2 {
margin-right: 0;
}

.builder-gallery-columns-3 .builder-gallery-item {
width: 100%;

The percentage of the width was different. Does anyone know the old percentage so I can change it back? Now the pictures on the frontpage of my site are huge :S
