a person need 64 credits and they have 24 what percent of credits is needed

Question

i need it in % thank you

Answer 1

They have 24 credits.  They need 64 credits.  They need 64 - 24 = 40 more credits

If the question is "what percent of the total credits do they still need?" then:

Since they need 40 more credits, the percent of the total credits they still need is (40/64) * 100 = 62.5%

If the question is "what percent more than what they already have do they need?" then:

since they need 40 more credits and they already have 25 credits, they need (40/25) * 100 = 160% more credits than what they have now.
