What is greater 0.8 or 7 over 8?

Answer 1

7 over 8 would be greater because if you change 7/8 into a decimal, it will become 0.875, which is greater than 0.8.

Answer 2

0.8 & 7/8

Two methods

#1 Convert all to decimals

#2 ; convert all to fractions.

Method '1'

7/8 = 0.875

Hence 0.8 & 0.875

Bring both to the same number of decimal places.

0.800 & 0.875

Drop the prefix zero and the decimal point ; hence 800 & 875

Clearly 875 > 800 Hence it follows that 0.875 > 0.8 ==> 7/8 > 0.8

Method '2'

0.8 = 8/10 = 4/5 & 7/8

Bring both denominators to a common factor, in this case '40' as both '5' & '8' are factors of '40'.

The bring the numerators to the equivalent value

Hence

4/5 = 32/40

7/8 = 35/40

Compare the numerators ; clearly 35> 32

Hence it follows 7/8 > 4/5 ==> 7/8 > 0.8
