37-(-15)×30℅+-(3/8)-3×(-8)

37-(-15)×30℅+-(3/8)-3×(-8)

$37 - ( - 15) times 30% + ( - frac{3}{8} ) - 3 times ( - 8) \ = 37 - ( - 450%) + ( - frac{3}{8} ) + 24 \ = 37 + 4 frac{1}{2} - frac{3}{8} + 24 \ = 37 + frac{9}{2} - frac{3}{8} + 24 \ = frac{296 + 36 - 6 + 192}{8} \ = frac{518}{8} \ = 64 frac{3}{4}$

$= 52 times frac{30}{100} - frac{195}{5} \ = frac{390}{25} - frac{195}{5} \ = - frac{585}{25} = - 23 frac{10}{25}$

maaf kalo salah
