• B. 150%
• C. 1.5%
• D. 30%

Answer 1

The correct option is B 150%

To convert the decimal to percentage form, express the decimal as a fraction then express the fraction in terms of per hundred.

1.5 in fraction form is $\frac{15}{10}$ = $\frac{150}{100}$

Convert it to percentage by multiplying by 100%,

$\frac{150}{100}$ $\times$100% = 150%
