Question

Decrease 5 1/4 m by 50 cm. Answer has to be m.

Answer 1

5 1/4 m is 5.25m. 50cm is 0.5m.
So 5.25 - 0.5 = 4.75m, or 4 3/4 m as a fraction

Answer 2

`4(3)/(4)` m

Explanation:

1 meter = 100 centimeters

50 cm =
`(50)/(100) m`

50 cm =
`(1)/(2) m`

Original length =
`5(1)/(4)=(21)/(4) m`

Decrease the original length by 50 cm

So, Length =
`(21)/(4) -(1)/(2)`

=
`(21-2)/(4)`

=
`(19)/(4)`

=
`4(3)/(4)`

Hence new length is
`4(3)/(4)` m
