Question

6. Use words and numbers to explain how the number 0.4 can mean 40/100 and 4/10 at the same time

Answer 1

0.4 is the decimal form of
`(4)/(10)`, which means that 4 ÷ 10 = 0.4, shown below.

If you multiply the numerator and denominator of
`(4)/(10)` by 10, you would get
`(4*10)/(10*10) =(40)/(100)`. This is equal in value to
`(4)/(10)` because 40 ÷ 100 = 0.4.

Answer 2

Answer:They are all the same because 40/100 divided by 10 on both sides is just 4/10 and 4/10 as a decimal is equal to 0.4
