I was writing this in my paper.
70 million photos and videos are sent daily on Instagram, while Louvre Museum has 300,000 objects [Kaplan and Haenlein, 2010], which is merely 0.4% of Instagram in quantity.
But the sentence seems long and the structure is weird. I think I should combine Louvre's object and percentage in one sentence, but I'm not sure how to rephrase it.
Could you please help me rephrase it? Any ideas/suggestions would be appreciated. Thanks a lot.
