Question

Помогите пожалуйста, номер 545.

Answer 1

1) $\frac{6}{25}-0.238=\frac{6*4}{25*4}-0.238=\frac{24}{100}-0.238=0.24-0.238=0.240-0.238=0.002$

2) $\frac{237}{250}+0.052=\frac{237*4}{250*4}+0.052=\frac{948}{1000}+0.052=0.948+0.052=1$

3) $0.35 + 1 \frac{7}{8}= 0.35 + \frac{15}{8}= 0.35 + \frac{15*125}{8*125}=0.35+\frac{1875}{1000}=0.35+1.875=2.225$

4) $9 \frac {329}{500}-8.658=\frac{4829}{500}-8.658=\frac{4829*2}{500*2}-8.658=\frac{9658}{1000}-8.658=9.658-8.658=1$
