1.) 1 2/5 – 0,25 + 1/22.)0,45 + (1 1/5 – 75%)bantu jwb yuu pke cra yy

Jawaban:

$1 frac{2}{5} - 0.25 + frac{1}{2} = (frac{7}{5 } - frac{25}{100} ) + frac{1}{2} = frac{140 - 25}{100} + frac{1}{2} = frac{115}{100} + frac{1}{2} = frac{115 + 50}{100} = frac{165}{100} = 1 frac{65}{100} div 5 = 1 frac{13}{20}$

$0.45 + (1 frac{1}{5} - 75%) = 0.45 +( frac{6}{5} - frac{75}{100} ) = 0.45 + frac{120 - 75}{100} = 0.45 + frac{45}{100} = frac{45}{100} + frac{45}{100} = frac{90}{100} = 90%$
