2.66:3.8-0.81 x 0.12 + 0.0372

Answer 1

2.66:3.8=0,7

0.81 x 0.12=0,0972

0,7-0,0972+0,0372=0,64

Answer 2

$2.66 \div 3.8 - 0.81 \times 0.12 + 0.0372 = \frac{266}{100} \times \frac{10}{38} - \frac{81 \times 12}{100 \times 100} + \frac{372}{1000} = \frac{7}{10} - \frac{972}{10000} + \frac{372}{10000} = \frac{7000 - 972 + 372}{10000} = \frac{6400}{10000} = 0.64$
