Question

peter ran 7/2 km erik ran 1/4 km more than peter andy ran 25/12 km less than erik how far did andy ran

Answer 1

Step-by-step explanation:

LCM of 2 and 4 = 4

Peter ran 7/2km = 14/4 and Erik ran 14/4 +1/4= 15/4 km

Andy ran 45/12-25/12km = 20/12 km = 5/3 km

Answer 2

Andy ran

$1 \frac{2}{3} \: \: km$

Step-by-step explanation:

Given :

Peter ran = 7/2 km.

Erik ran 1/4 km more than Peter.

Andy ran 25/12 km less than Erik.

To find :

How far did Andy run ?

Solution :

Distance ran by Peter = 7/2 + 1/4

= 14/4 + 1/4

= 15/4 km.

Distance ran by Andy = 15/4 - 25/12

= 45/12 - 25/12

=20/12 km.

= 5/3 km.

=

$1 \frac{2}{3} \: \: km.$
