Troy says that 0.9>0.90 because tenths are greater than hundredths. Keith says that 0.9<0.90 bra side 90 is greater than 9. Is either Troy or Keith correct?Explain

None of them is correct

0.9=0.90

Step-by-step explanation:

0.9>0.90 (not valid)

0.9<0.90 (not valid)

1. when dealing with decimals, the digits on the left hand side of the decimal point is a whole number.

The digits at the right hand side are considered individually.

2. the place value of the first digit is tenth, next is hundredth

3. if the last digits at the right hand side of the decimal point are zeros, then they are insignificant having no place value.

Hence, 0.9 is not greater 0.90

0.9 is not also less than 0.90,

because, the '0' at the right hand side of the decimal point, immediately after 9 is insignificant.

Therefore, 0.9=0.90

glide reflection.

its mainly because the pattern will be infinite and will never end. it will look like a gilder or like a filpbook when set to motion.

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y
