$\huge\underline{\underline{\bold{\red{A}\green{n}\orange{s}\pink{w}\blue{e}{r}}}}$

a) 37% + _ = 100%

• let the percentage be x ,
• then, 37% + x = 100%
• x = 100% - 37%
• x = 63%
• percentage is 63 % .

b) 55% = 100% - _

• let the percentage be x,
• then, 55% = 100% - x
• x = 100% - 55%
• x = 45%

c) 40% + 30% + _= 100%

• let the percentage be x,
• then, 40% + 30% + x = 100%
• 70 % + x = 100%
• x = 100% - 70%
• x = 30%

Let's do verification …

$we \: know \: that \: every \: thing \: is \: 100\% \\ or \\ we \: also \: know \: that \: sum \: of \: all \: percent \: is \: equal \: to \: 100\%$

a) 37% + 63% = 100%

b) 55% + 45% = 100%

c) 40% + 30%+ 30% = 100%

hence, we have done !
