Question

Jayne says that 0.45 is equal to 4/10. Is she correct? Explain.

Answer 1

$0.45 = \dfrac{45}{100}$

$\dfrac{4}{10} = \dfrac{4 \times 10}{10 \times 10} = \dfrac{40}{100}$

$\dfrac{45}{100} \neq \dfrac{40}{100}$

They are not the equal.

Answer 2

No, 4/10 is equal to 0.40 and not 0.45 since 4/10 goes in tens.
