Question

about 0.4 of a biology class will be going on a field trip . write the decimal as a fraction in simplest form .

Answer 1

0.4 is $\frac{4}{10}$ and that simplified is $\frac{2}{5}$ because you take the GCF or Greatest Common Factor, which is two, and divide both parts of the fraction taking $\frac{4}{10}$ and turning it into $\frac{2}{5}$
