I’m not rly sure what it means by flipping the card …. I’m assuming there’s more to this question but if it’s what I think it is the only way this equation will be true is by switching the + Symbol to - (subtraction) which would be 1-2= 3-4 since it would 1=1 making the equation true
I’m more than happy to help you
16:40 is basically 16/40
16/40 in lowest terms is 2/5
Hope I helped...
