Question

An electrician has 4.1 meters of wire.

a. how many strip 7/10m long can he cut?
b. how much wire will he have left over

Answer 1

we know that

`4.1m= (41)/(10)m`

Part a) how many strip 7/10m long can he cut?

divide
`(41)/(10)` by
`(7)/(10)`
so

`( (41)/(10))/( (7)/(10)) = (41)/(7) \\ \\ =5.85 \\ \\ =5strip`

the answer part a) is

`5strip`

Part b) how much wire will he have left over

`5* (7)/(10) =3.5m`

`3.5`m of wire wil be used in cutting possible
`(7)/(10)`m pieces

so
wire left over will be

`4.1-3.5=0.6 m`

the answer Part b) is

`0.6m`

Answer 2

a)He can cut 5 strips of of 7/10m.

7/10=0.7m

0.7*5=3.5m
3.5m of wire wil be used in cutting possible 7/10m pieces.

b)Leftover will be 0.6m.
4.1-3.5=0.6m
